Problem or Enhancement Description

Req

v1.4.00f

02/22/08

PTF with cumulative fixes for v1.4.00

807

02/19/08

Publish updated macro KSIRD.MAC with 2 new fields for low and high branch height used in AVL balancing of KSIT tree with KSIR nodes.

DSH

808

02/20/08

Correct pz390 as follows:
1) Prevent trap on trace of LA when address higher than max memory and show value of -1 instead.
1) Prevent HFP and BFP underflow exception for multiply operations when one of the two operands is exactly zero or for divide when the divident is exactly zero. See new contest problem mfacc\P12DSH2.MLC to calculate standard deviation in HFP and P11DSH3.MLC to calculate standard deviation using only DFP instruction. All solutions correct to within 33+ decimal places.

DSH

v1.4.00e

02/18/08

PTF with cumulative fixes for v1.4.00

806

02/08/08

VSAM fixes and enhancements:
1) Add automatic balancing of insert KSIT tree using AVL balancing technique to maintain even tree depth after inserts.
2) Add verification of all double links between KSIT and KSIR's.
3) Add verification of all KSIR heights in KSIT balanced tree.
4) Add AVL statistics to VSAM statistics for STATS option
5) Improve VCB cache size for optimizing VSAM I/O
4) Add regression test vsam\test\KSF2TST4.BAT which tests inserting 1000 records in pseudo random sequence and then fetching them by key sequentially to test AVL rotations LL, LR, RR, RL and verify KSIT tree has only 10 levels (2**10=1024). With cache on, the resulting file I/O to insert and then fetch 1000 records is about 10,000 or 10 I/O's per record. VSAM KSDS insert can be used as a sorting tool with the efficiency comparable to shell sort where I/O is proportional to N * log2 N.

DSH

v1.4.00d

4. List all changed options on STA file.
5. List all macro/copybook file cross reference on STA file.
6) Add ECHO OFF to all batch commands such as ASMLG.BAT to suppress output listing of BAT file commands.
7) Echo start and stop messages on console and ERR file regardless of CON setting and include z390 and J2SE version on start message.
8) Only put copyright and license msgs on PRN, LST, and LOG files.
9) Change the command files ASMLG.BAT, ASML.BAT, ASM.BAT, LINK.BAT, and EXEC.BAT to set ECHO OFF so the only messages appearing on the GUI or command line log display are the START and STOP messages if CON option is off.

756

12/09/07

1) Fix all file parameters to accept relative or explicit path for file including paths with double quotes if needed, and paths starting with drive and no explicit path (i.e. relative path on specified drive.

12/19/07

Change Z390 GUI to force line split before sending "EXIT" to task for termination.

768

12/22/07

1. Correct LXR failing due to not setting correct floating point cache status for 2nd register in pair.
2. Correct square root routine to use rounding from contest when adjusting scale factor to even value.

DSH

769

12/23/07

Change az390 to just issue error rather than abort for invalid ASCII characters in source statements. Check * comment lines for ASCII as well.

770

12/27/07

Add lz390 linker option to turn off autolink via NOAUTOLINK which then requires explicit includes for all external references.

771

12/27/07

Correct az390 to allow 0 address field in CCW's.

772

12/27/07

Correct LISTCALL MEXIT generation to prevent truncating macro call reference number which matches previous MCALL.

773

12/27/07

Issue abort error 224 if OPSYN table exceeded (It was ignoring requests at limit).

774

12/28/07

mz390 fixes:
1) Correct SETC expression parser to handle (exp)'string' where expression result is 0 resulting in an empty duplicate string versus a null string.
2) Correct compound AIF pseudo code execution to exit on first true test condition. It was erroneously branching on last true test condition.

776

Correct pz390 instruction processing errors discovered while testing z390 Mainframe Assembler Coding Contest problem #10 solution submitted by Mats Broberg at SEB Sweden:
1) Correct packed decimal instructions to switch from Java internal long to BigInteger when result value may exceed limits of long.
2) Add check for DLG and DLGR overflow.

DSH

782

01/08/08

Stop the interval timer process at exit from ez390 to prevent occasional thread exceptions during shutdown of ez390.

DSH

786

01/11/08

Change az390 to generate decimal floating point constants with preferred exponent of -2 if possible without loss of significance. Previously DFP constants were generated with smallest quantum which is arithmetically equivalent. See IBM Journal reference article. See updated regression tests linklib\TESTFP1.MLC, rt\test\TESTDFP1.MLC, and rt\test\TESTCFD1.MLC which have been changed to use arithmetic compares versus CLC compares to allow for constants and calculated results to compare equal even thought they have different canonical forms. The lastest POP describes the preferred canonical forms for different DFP operations in table 20-4.

787

01/13/08

Correct support for DFP un-normalized instructions:
1) Flush cached un-ormalized result to register for following store.

790

01/14/08

Include new ZMFACC macro used for portability of z390 Mainframe Assembler Coding Contest solutions across the following environments: z390 running on J2SE on Windows or Linux, Hercules MVS 3.8 for Windows or Linux, z/OS, z/VM CMS, or VSE.

DSH

v1.3.08g

12/09/07

Cumulative fixes and enhancements for v1.3.08

746

12/01/07

Move generated BAL comment for macro calls before initial load to more easily identify source of any macro loading errors or missing macro label warnings. Also correct source file cross reference line number reference errors in TRM trace file for TRACEM.

747

12/01/07

add options to control level of z390 checking in RPI 747 as follows:
CHKSRC(n) where n is as follows with default CHKSRC(1):
0 - no checking for ASCII (allows non-printable ASCII characters in source which may or may not result in errors later in assembly or execution depending on whether they appear in comments or in character strings intended to be hex EBCDIC characters. These need to be in X'...' format for portability.
1 - check for any non-printable ASCII characters in MLC source.
2 - check for any non-printable ASCII characters in all MLC and macro source code. Note COPY sources are always checked along with files that include them.

CHKMAC(n) where n is as follows with default CHKMAC(0):
0 - no checking for missing macro labels and no checking for source statements after final MEND.
1 - check for missing macro labels during loading and generate warnings.
2 - check for missing labels and check for any source statements after final MEND and generate warning.

Misc related fixes:
1. Correct line number reference for bad character error messages.
2, Correct az390 to generate private CSECT for any opcode prior to first section declaration.
See usage on rt\test\TESTERR1.MLC.

749

12/02/07

Misc. fixes for az390 assembler:
1) Issue error for EQU expression referencing itself (X EQU X).
2) Issue error for literal with forward referenced symbols in modifiers such as =C(SECTLEN)' '. Alternate code paths could change value of lookahead symbol resulting in erroneous literal. Note HLASM does not perform lookahead for literal references whereas z390 always does lookahead for entire source file during loading into memory prior to pseudo code generation. See updated rt\test\TESTERR2.MLC

750

12/03/07

Corrections and enhancements to VSAM KSDS support:
1) Trace RPL after each function for TRACE(V)
2) Correct processing for POINT using KGE and generic key.
3) Correct GET without SEQ returning not found, and GET SEQ returning second record instead of first with KGE.
4) Add KEYLEN= parm support to MODCB.
5) Split RPLFLAG word into 4 bytes with equates in RPLD.
See new vsam\test\KSF1TEST.MLC with KSDS retrieval using full keys and KGE generic keys.

751

12/04/07

Add CICS response code DFHRESP(EXPIRED) = F'31'.

754

12/08/07

Issue error and exit macro after ACTR limit error versus abort. Also correct macro pseudo code AGO to decrement ACTR count.

v1.3.08f

11/30/07

Cumulative fixes and enhancements for v1.3.08

742

11/17/07

1) Issue error message and abort if option is not recognized.
2) Add @filename option to include options from free form text file with optional comments starting with *. Default file name suffix is OPT, and search path is SYSOPT which defaults to program directory. SYSCPY changed to default to SYSMAC which defaults to program directory. Any number of @files can be specified and they can be nested. See rt\test\TESTOPT1 regression test.
3) If any option with directories or files is specified and it starts with +, then concatenate with any prior setting for that option else replace it. Ignore + if it is the first occurrence of option.

743

11/17/07

Misc. mz390 corrections:
1) Correct mz390 to allow comment on macro proto-type statement following positional and keyword parms.
2 )Correct mz390 to allow comments without leading comma on PR just like it does with 12 other instructions with no operands.
3) Set attribute type for CNOP label to 'I'. Note length is unknown during lookahead mode.
4) Correct PUNCH processing to support comments following '...'
See rt\test\TESTASM1.MLC regression test.

744

11/24/07

Change mz390 and az390 to issue error if non-comment source statements contain non-printable ASCII characters. This will help identify any character constants such as C'..' which must be converted to hex format X'....' for portability between EBCDIC and ASCII based host system. See rt\test\TESTERR1.MLC

745

11/25/07

Add mz390 support for the AREAD options CLOCKB, and CLOCKD and ignore options NOPRINT and NOSTMT. See rt\test\TESTASM1.MLC regression test.

v1.3.08e

11/17/07

PTF with cumulative fixes for v1.3.08

738

11/12/07

Correct LAY instruction trace to prevent address exception on attempt to fetch addressable memory beyond real memory.

739

11/12/07

Correct RRDS and KSDS sequential access versus key access to test RPL option SEQ versus KEY.

MM,DE

740

11/14/07

Misc. changes:
1) Allow mismatch between proto-type and macro file name with just a warning message.
2) Add option CHKMAC to check all macros during loading for excess statements beyond the final MEND statement.

v1.3.08d

11/16/07

PTF with cumulate fixes and enhancements for v1.3.09

735

11/12/07

Corrections to new linker LNK support plus a few misc. changes:
1) Change LNK to LKD to avoid conflict with Windows shortcuts
2) Ignore CTRL-Z (hex 1A end of file codes in LKD source code
3) Prevent trap when INCLUDE DDNAME is not defined
4) Issue message ignoring all unrecognized command such as SETOPT and PARM(....)
5) Check for explicit .OBJ on lz390 file parm and ignore LKD
6) Assign default starting address of load module to matching EXTRN if there is no matching CSECT/ENTRY in load module.

737

11/11/07

Misc. corrections and enhancements:
1) Add mz390 warning message if non-comment type statements found after END statement with option ASM.
2) Add option STATS(filename) to append all statistics output from mz390, az390, lz390, and ez390 to filename.STA. Use of this option turns off statistics as comments at end of BAL, PRN, LST, and LOG files. Spectify NOTSTATS for no statistics at all.
3) Correct spelling of "version" in IVP message.
4) Correct superzap spelling on command prompt
5) Correct superzap.bat rem, spelling, and remove pause
6) Correct superzap display of each command read once
8) Correct superzap SYSIN file I/O error to display error message and exit rather than issue user abend.
9) Correct z390 GUI interface to route all input to running CMD task until it terminates. Enter exit or ctrl-break to force CMD end.
10) Update superzap web page documentation
11) Correct az390 assembler to handle Enn exponent modifier on F and H type constants.
12) Prevent trap on ASCII character literal conversion to EBCDIC for hex codes 00-ff. ASCII with high bit maps to same EBCDIC character as ASCII with no high bit. When converting EBCDIC source to ASCII for use with z390, translation use a tool that reports any hex literals with non-ASCII characters as errors. These much be converted from C'...' to X'....' format for portability.

v1.3.08c

11/09/07

PTF with cumulative fixes for v1.3.08

732

10/27/07

Add new lz390 linker optional input command file named linkfile.LNK where linkfile is the linker parm anme. The LNK command file may contain 1 or more sets of the following commands to create 390 load modules:
1) INCLUDE DDNAME(name) - default is linkfile.obj
2) ALIAS name - default no alias created
3) ENTRY name - default is offset 0 in linkfile.obj
4) NAME name(R) - default is to create single linkfile.390
The (R) is assumed if not present. The default directory for the LNK command file is the same as the MLC source default directory. ALIAS will generate 390 stub file which simply contains up to 8 character ASCII name of the real 390 program to execute. These stub 390 files contain no OS dependent path characters and are portable between Windows and Linux. The ALIAS and the real 390 program will be located using SYS390 directory option setting.

733

10/27/07

Consolidate all the TRACE options into one option using TRACE(AEGLMQTV) where letters represent the following:
A - trace az390 assembler creating .TRA file
E - trace ez390 instruction execution creating .TRE file
G - trace all GETMAIN/FREEMAIN requests on .TRE
L - trace lz390 linker creating .TRL file
M - trace mz390 macro propcessor creating .TRM file
P - trace nz390 macro pseudo code generation/execution on TRM
Q - trace all QSAM DCB I/O data transfers on .TRE file
T - trace all TCPIO messaging transfers on .TRE file
V - trace all VSAM ACB I/O data transfers on .TRE file
The existing TRACE option is the same as TRACE(E) and the TRACEALL option is the same as TRACE(AEGLMQTV)

v1.3.08b

11/07/07

PTF with cumulative fixes for v1.3.08

724

10/22/07

Change REPRO VSAM utility support as follows:
1) Support the following sequential unloaded file formats:

RECFM	Prefix words	Record	Notes
EF	none	records up to 2 GB	Default for fixed ESDS/KSDS (a)
EV	LLLL	records up to 2 GB	Default for variable ESDS/KSDS (a, b)
RF	RRN	records up to 2 GB	Default for RRDS, (a, c)
RV	LLLL,RRN	records up to 2 GB	Default for VRRDS (a, b)
F or FB	none	records up to 32760	(d)
FT	none	ASCII text records	(d), Converts to EBCDIC
V	LL00	records up to 32760	(d,e)
VB	BB00,LL00	records up to 32760	(d,e,f)
VT	none	ASCII text records	(d), Converts to EBCDIC

Notes:
a) The default formats (EF, EV, RF, and RV) all use QSAM fixed format I/O changing the full word DCBLRECLF to read or write up to 2 GB at once.
b) LLLL is full word record length up to 2 GB including 4 or 8 byte prefix.
c) RRN Relative Record Number is full word starting with 1 for first record.
d) F, FB, FT, V, VB, and VT alternate standard QSAM formats may be used by coding [RECFM=xx] following file name on corresponding INFILE or OUTFILE set statement. Note unloading RRDS/VRRDS to alternate QSAM format file will skip unwritten records, and reload may assign different relative record positions form the original RRDS/VRRDS file.
e) LL00 is 2 byte record length including prefix followed by 2 byte zero.
f ) BB00 is 2 byte block length including prefix followed by 2 byte zero. One or more LL00 prefixes and records may appear in a block. Blocking is unnecessary as REPRO uses its own larger buffer to optimize performance.
2) Change VSAM RRDS structure to use VX0 index to point to non-null records with XRBA+1. Null records contain 0 XRBA index values just like VRRDS and KSDS. This saves space for sparse record files and simplifies detection of unwritten or deleted records.
3) Add REPRO buffer to reduce I/O's and improve performance using 500k buffer..
4) Add statistics showing record formats and total records.
5) Correct VSAM to raise no record found when randomly reading empty slot.
6) Correct RRDS to return RRN Relative Record Number starting with 1.
7) If RRN = -1, set to next RRN at end of file.
8) Return invalid request response for RRDS option ADR and ESDS option KEY.
9) For RRDS get with KEQ return no record found if null record.
10) For RRDS get with KGE return next non-null record.
See updated RRF1TEST, RRF1SKP1, RRF1REPO, RRV1TEST, RRV1SKP1, and RRV1REPO regression tests in vsam\test.

725

10/22/07

Remove -Xmx option from mz390.bat (no longer needed with 2GB memory on PC). See updated EZ390.BAT comments documenting all the options available. Add link to J2SE runtime options documentation.

MM/DSH

726

10/23/07

Suppress error 187 indicating first assembly address change if there are previous errors reported or the TRACE option is on.

728

10/23/07

Enhancements to mz390/az390 to support assembly of Waterloo Assembler G source code available on the web from SHARE files at www.cbttape.org file #593 (43k lines of code in 44 MLC files with 2817 lines of macro code in 73 MAC macro files and 1 CPY copy file):
1) Rename MVS macro DLETE.MAC to DELETE.MAC.
2) Add support for ICTL start, end, continue source format control statement in the mz390 loading stage. See ASMG source module ASMGBUFF.MLC as exmple using ICTL 1,71,20 which successfully assembles with continuation lines starting in col. 20.
2) Ignore ICTL and ISEQ statements in the az390 assembly process. The BAL file generated by mz390 is in standard ICTL 1,71,16 format with any ICTL and ISEQ statements included but ignored.

729

10/26/07

Add EXEC CICS DFHRESP response code ILLOGIC with value F'21'. See updated rt\test\TESTCIC1 regression test.

730

10/26/07

Correct LOG(filename) option to override the default program name for the LOG, TRE, and ERR execution output files using the same path as the program. If there is no program path specified as in the case of REPRO and other utilities, then the current directory is used for LOG(files). This enables creation of separate files for multiple programs with the same name running concurrently via CMDPROC started tasks.

731

10/26/07

Change processing of CMDPROC started task output as follows:
1) Optimize the methods used to sent and receive messages to/from started tasks using line at a time versus character at a time methods.
2) Add option MAXLOG(mb) with 1 MB default. When the visible GUI log exceeds the MAXLOG limit, the visible log will be truncated by 50% to prevent exceeding available memory.
3) Add option MAXQUE(messages) with 1000 default. When the number of started task output messages queued in memory exceeds this limit, all output from started tasks is copied to the parent's log file to prevent exceeding available memory.
4) Add keyword option CMDLOG=YES to CMPROC macro for use with START command to indicate that parent task should automatically route any started task output to the parent log file. Log messages from started tasks will be prefixed with CMD ID=N. If CMDLOG=NO is specified, the parent task must issue CMDPROC READ commands to retrieve messages from the memory resident started task output queue.
5) Issue yield after each output message from started task svc services to allow parent task to process message or copy message to the parent's log file. If the memory queue reaches MAXQUE limit for any reason, then messages will be copied to LOG and will no longer be available via CMDPROC READ commands.
6) Correct error message 18 to say maximum trace file size exceeded instead of bal. To increase maximum output file sizes from default of 50 MB, add option MAXSIZE(100) etc.
7) Add support for CMD subtasks running J2SE programs to request parent task shutdown due to abort error such as file error. Any CMD subtask can request parent abort by sending message "z390_abort_request" to standard output. This allows CICS to shutdown gracefully without leaving hung local terminal processes.
See updated rt\test\TESTCMD1 and TESTCMD2 regression tests with new CMDLOG=NO added.

Corrections to GUAM support for TN3270 screen used by CICS:
1) Correct TGET with RC=4 returning data in buffer unexpectedly.
2) After CTRL-C clear screen, set cursor at (1,1). This is to correct intermittent problem with cursor returning to cursor location from previous TPUT.
3) Correct code to prevent trap on bad index during interval timer exit for checking WTOR reply and timeout limits.

713

10/04/07

Corrections in order to successfully install z390 v1.3.08 on Ubuntu Linux 6.06 LTS and run all regression tests:
1) Change iz390.java to match file name case for Z390.IVP.
2) Correct RTLINK1.BAT to use lower case mac+linklib for UNREF assembly.
3) Correct RT.BAT to remove RTUTIL references and add vsam DIFF.TXT file for Linux.
4) Correct cmd.pl perl script to correctly handle SET commands where value contains = such as [RECFM=FT] in REPRO commands for testing VSAM.
5) Add new command COMP1.BAT to handle both Windows and Linux file compares using fc or diff creating difference file and setting rc to non-zero if files have differences other than while space.
6) Correct file I/O to check for relative path and prefix with current directory as defined in J2SE since Linux and Windows are inconsistent with respect to current directory used by file handler.
7) Update cmd.pl to pause and then exit if unknown BAT command attempted.
VS reported error in perl scripts but with the corrections above I was able to run all regression tests including vsam with no errors on Linux with J2SE 1.5.0_13.

Add initial KSDS support.
1) See vsam\demo\KSF1RPO1.BAT which uses REPRO to load KSF1NAME cluster and primary index from text file KSF1NAME.TF1 containing 6 records with name, address, etc. Then it uses REPRO to unload fKSDS file to ascii text file KSF1NAME.TF2 and compares it to the original input file.
2) See vsam\demo\KSF1DEMO.BAT which reads 6 records in KSF1NAME KSDS file in reverse order via primary key access.
Run RTVSAM.BAT to run all VSAM regression tests and demos.
3) See vsam\demo\KSF1SKP1.MLC which does POINT for key MQ with RPL option KGE and then reads and lists records sequentially to end of file.

2) Store RBA or XRBA in RPLARG on sequential GET or PUT for ESDS and check limit.
3) Check file size limit on all VES reads and writes.
4) Check RBA/XRBA for fixed ESDS for multiple of record length. There are no other consistency checks of positive RBA/XRBA for variable length ESDS or KSDS files currently.

Change ESDS and RRDS support as follows:
1) Require use of POINT to set ESDS current RBA/XRBA position prior to GET for SEQ FWD or BWD RPL's. Allow use of RBA/XRBA of high values for POINT to indicate end of file. See updated ESF1SKP1 and ESV1SKP1 regression test changes.
2) Require use of POINT to set current position prior to GET for SEQ FWD or BWD. Support with LRD or high value record number or RBA/XRBA to position to end of file. See new ESF1SKP1, ESV1SKP1, RRF1SKP1 and RRV1SKP1 regression tests.
3) Change ACB and RPL option DIR to KEY for random access to RRDS and VRDDS by record #. See all demo and test RRDS/VRRDS programs.
4) Change TRACE format for both VSAM and TCPIO svc's to show the name of the specific operation being requested based on opcode in R0. For example you can now search for "VSAM POINT" in trace.
5) Change positioning support to always store current VES or VX0 XRBA address in RPLCXRBA field. Store last record XRBA in RPLLXRBA else store -1. Reset RPLLXRBA to -1 and RPLCXRBA to 0 when new or reopened ACB is detected for RPL.
6) For ESDS sequential access, return current RBA/XRBA for each record in RPLARG. See updated ESF1SKP1 and ESV1SKP1 regression tests.
8) For RRDS and VRRDS sequential access skip null records created by system and return relative record # in RPLARG. See updated RRF1SKP1 and RRV1SKP1 regression tests.

1) Change OPEN to generate required DCBD for option flag refs.
2) Correct RPLD name of RPLID field.
3) Add ZGENMACF and ZGENOPTD macro to support MACRF= and OPTCD= option bit generation shared by ACB, RPL, and MODCB.

696

09/15/07

Correct misc. VSAM errors:
1) Correct ZMODCB error to handle 1 byte fields which caused error MNOTE trying to change MACRF or OPTCD fields.
2) Correct REPRO to verify successfully loaded catalog file is a VCDT catalog before assuming DDNAME is a VSAM catalog reference.
3) Add support for MODCB default option parms for RPL OPTCD - FWD to turn bit off in RPL with BWD set. Note all the required OPTCD option bits in ACB MACRF or RPL OPTCD must be specified since MODCB replaces the entire field with new options specified. Add support for RPL= and ACB= which means that the RPL fieldfor ACB address is being updated.

697

09/17/07

Correct QSAM\VSAM related I/O support as follows:
1) Correct DCB variable GET and PUT to allow 5 byte variable length records with 1 byte of data. Previously errors 28 and 35 were issued for 1 byte variable length records in error.
2) Change REPRO to accept override of QSAM RECFM for fixed or variable length from default of F or V to FT, FB, VT, or VB by specifying the RECFM required in brackets after file name. For example: SET INFILE=TESTVT.TF1[RECFM=VT]. See vsam\test\ESF4REPO.BAT and ESV5REPO.BAT regression tests.
3) Correct feedback for ESDS invalid RBA to use reason code x'32' versus x'c4' which is for RRDS only
4) Correct RPL processing init to always refresh ACB and VCLR fields. Correct ACB. Correct ACB processing init to always refresh VCLR fields as well.
4) If ESDS RPL has ADR and SKP, then set current position on each RBA/XRBA get for possible following SEQ GET. For BWD be sure both ADR and SEQ RPL's also have BWD set. See updated vsam\test\ESF1SKP1.MLC and ESV1SKP1.MLC regression tests.
5) Add option TRACEQ to trace all QSAM GET/PUT file I/O similar to TRACEV for VSAM file I/O.
6) Correct QSAM VT input support to handle ascii line with no characters other than cr,lf and create 5 variable length input record with single space since 5 is the minimum QSAM record length. See regression test vsam\test\ESV5REPO.BAT.
7) Set R15=0 return code for SHOWCB, TESTCB, MODCB.

v1.3.07d

9/14/07

PTF with cumulative fixes for v1.3.07 and VSAM enhancements

672

08/24/07

Correct and enhance VSAM ESDS and RRDS support as follows:
1) Correct ESDS and fixed length RRDS to read and write directly to VES data file with no VX0 index required. RBA and XRBA now point directly to VES records.
2) Add ESDS update option UPD. Updates must be for same length record in place via PUT after successful GET. See new regression tests vsam\test\ESF2TEST and ESV3TEST tests.
3) Add ESDS option BWD for fixed and variable length sequential read backwards. For variable length ESDS, this requires adding redundant record length following each record in order to sequentially traverse file backwards with no VX0 index. See regression tests vsam\test\ESF3TEST and ESV4TEST.
4) RRDS variable length files (also known as VRRDS) will continue to use VX0 to map relative record # into XRBA for VES data file access. Rewriting VRRDS record with different length causes record to be written at end of VES leaving prior record area as dead space until next unload/reload. See regression test vsam\test\ESV3TEST.
5) Correct to always use RPL flags vs ACB flags to determine which type of access to use. Correct RPL macro to issue error for undefined options. Verify RPL vs ACB for MOD,TEST,SHOW.

MM/DSH

694

09/11/07

Add new option ERRSUM to list critical error summary on PRN, ERR and console. Missing macros and copy files are listed if any. If none, then any remaining undefined symbols are listed. This option highlights missing macros and copybooks as first priority to correct. Once all macros and copybooks are found option ERRSUM will list any remaining undefine symbols which usually indicate a missing macro or copybook such as a DSECT. This option is automatically turned on by the macro assembler when missing macros or copy files are detected. To override this option, specify ERR(0) to force assembly regardless of critical errors. This option may need to be used several times to find and fix nested missing macros and copybooks. Any remaining undefined symbols in an assembly now appear in the symbol table with TYPE=UND. For an example try assembling the REPRO VSAM utility with the command ASM linklib\REPRO SYSMAC() SYSCPY() which suppresses the default libraries and causes ERRSUM option to be turned on to show 2 missing copy files and 24 missing macros causing 25 undefined symbols.

695

09/12/07

Correct mz390 macro processor to replace single null macro call parameter on inner macro call with comma if space delimited comments follow the parm to prevent the first word in comments from being parsed as call parameter in error. See updated regression test rt\test\TESTMAC1.

v1.3.07c

09/07/07

PTF with cumulative fixes for v1.3.07 and new VSAM catalog

681

08/20/07

Redefine VCDT from VSAM Cluster Definition Table for single VSAM file to VSAM Catalog Definition Table (VCDT) which is created using multiple DEFINE macros to define a catalog with multiple base clusters, alternate indexes, and paths. The DDNAME on ACB points to the VCDT catalog loadable file with optional dot suffix defining name of entry to open. Alternatively the ACB name field is used to find base cluster or path entry in the catalog. This was requested by Melvyn and provides more flexibility and compatibility with existing VSAM application code. The new catalog supports UPGRADE option on each alternate index and supports using PATH pointing to base cluster with no updating of alternate indexes if desired. See updates to VCDTD, ACBD, and RPLD for new entries (application programs should use SHOWCB, TESTCB, and MODCB rather than these internal control blocks). All bit flags in these DSECTS have been changed to single byte values. See updates in vsam\demo and vsam\test to use new DEMCAT catalog for all the demos and TESTCAT for all the regression tests. Also see updates to vsam\test\ESV1TEST.MLC to verify RBA and XRBA read records randomly.

2) Add ESDS direct access by 4 byte RBA or 8 byte XRBA.
3) Support RPL=(reg) plus optional field SCON formats in MODCB, TESTCB, and SHOWCB. Add SHOWCB fields RBA and XRBA.
4) Change ACBD, RPLD, and VCDTD DSECT maps to split option flags into separate bytes with 1 byte EQU's.
5) Change ESF1 demo to use 3 - 80 byte fixed length records.
6) Change ESV1 demo to use 3 variable length records with 100, 200, and 300 bytes of data.
7) Add the following VSAM tests in vsam\test directory:
a. ESF1TEST - create and verify ESDS file with 3 fixed length records using sequential, RBA, and XRBA access.
b. ESF1REPO - load and unload ESF1 fixed length record ESDS file using REPO and verify.
c. ESV1TEST - create and verify ESDS file with 3 variable length records using sequential, RBA, and XRBA access.
d. ESV1REPO - load and unload ESV1 variable length record ESDS file using REPO and verify.

Update or add the following macros for initial VSAM ESDS support: ACB, ACBD, CLOSE, DEFINE, ERASE, GENCB, GET, MODCB, OPEN, POINT, PUT, RPL, RPLD, SHOWCB, TESTCB, and VCDTD. The DEFINE macro supports creation of loadable VSAM Cluster Definition Table (VCDT) which serves as equivalent of VSAM cluster catalog definition. The new ACBD, RPLD, and VCDTD macros provide DSECT layout of ACB, RPL, and VCDT control blocks, but for mainframe compatiblity only SHOWCB, MODCB, and TESTCB should be used to access ACB and RPL fields. A new utility linklib\REPRO supports loading or unloading VSAM file from/to QSAM files or anther VSAM file.

Work-around for Windows Vista to allow running z390 using default install directory in "C:\Program Files\....\z390" - Turn off Vista UAC option via the Control Panel, User Accounts dialog. This will allow spawned command line tasks to automatically obtain administrator permission required to access the "C:\Program Files" directory as of Vista updates applied between 07/08/07 and 07/15/07.

For more information about Vista UAC visit the following web sites:
Microsoft Vista User Account Control Option
Turning Vista UAC option off is hopefully a temporary solution to allow users to install z390 in the default directory on both XP and Vista and be able to achieve compatible results. The only other current work-around is to install z390 into a directory such as C:\z390 which is not protected like "C:\Program Files\..." on Vista.

Although turning off Vista UAC may appear to be increasing security risk, as long as security software such as Windows or Symantec fire wall is active, the risk should not be any higher that it was with Windows XP.

1) Return 64 bit size of file opened in R0 after successful open.
2) Support 32 bit DCB record length and block size using 2 new fields in DCB labeled DCBLRECLF and DCBBLKSIF. The low half of these fields overlap with existing DCBLRECL and DCBBLKSI at same offset for compatibility with existing 16 bit length applications. Note although 64 bit length files are supported by z390 now, memory is currently limited to 31 bits so the maximum single record length currently is limited to 31 bits.

TCPIO sockets support fixes and enhancements:
a) Close all open TCPIO ports during shutdown.
b) Add NOWAIT option for TCPIO RECEIVE which will return with RC=4 if no message is ready.
c) Eliminate LMAX parm from OPEN and just use LMSG on RECEIVE to limit input message size. Each RECEIVE will return up to LMSG bytes with actual bytes returned in R1. Increment MSG address, decrement LMSG by bytes read, and repeat RECEIVE until the desired number of bytes have been read. The number of bytes read will usually be the same as the number sent unless the network is stressed and the packet size has been reduced.
d) Support up to 20 connections on up to 10 server ports.
e) Add CONN= referencing register or RX location of 4 byte integer server connection id for use in SEND to server PORT. The server port RECEIVE returns the connection id in R2.
f) Add option TRACET to trace only TCPIO events on TRE file. The TRACE option defaults to include TRACET.
See updated SOA client server demo in soa\demo. See new SOA test programs in soa\test including client TESTMSGC.MLC and server TESTMSGS.MLC for manually testing multiple port connections. Multiple copies of the SOA demo client can also be run in parallel using the same single demo server.

Merge Linux support programs contributed by Martin Ward to support installation of z390 on Linux. With these changes the z390 file zip can be installed following this Linux Installation Guide:
1) Add "z390" perl script file to the z390 root directory. This script can be executed directly from Linux terminal command line or desktop launcher icon with no operands to start z390 GUI Interface or with options and file name to assemble, link, and/or execute assembler program. Changes to this script include:
   a) Set current directory to z390 directory before starting GUI
2) Add "cmd.pl" perl script file to the z390 root directory. This script is used to emulate cmd.exe Windows command processor to support execution of the following BAT file commands: rem, erase, copy, call, and java class execution. Changes to this script include:
    a) Support paths to bat files where paths must be correct case and
        bat file names must be uppercase. Default suffix is .BAT..
    b) Convert bat file "\" path delimiters to "/".
    b) Allow upper and lower case commands and labels in BAT files
    c) Support the following BAT file commands used in z390 tests:
         call, copy, dir file, diff dir1 dir2 file3, erase, exit, goto
         if errorlevel 1 goto label
         if errorlevel 1 pause (aborts on error currently)
         if exist file goto label
         pause (aborts after message currently), rem, set
3) Change z390\Doc directory to z390\doc for case consistency which was causing the "help, "guide" menu item to fail on Linux which is case sensitive so all paths and file names.
4) Change tz390 default text editor for Linux to "gedit" since it is already installed on base Ubuntu Linux and is a lightweight GUI editor similar menu to notepad plus support for multiple open files similar to Word.
5) Change all z390 RT BAT and data file names to upper case for consistency.
6) Change RTCOMP.BAT and RTLIST.BAT to test for Linux and use Linux diff command if running under cmp.pl on Linux.
7) Add option INSTALL(path) to debug z390 source with specified install path instead of default current path.
8) Change az390 to force macro names to uppercase for file search on Linux which requires all macro files to be uppercase.

467

09/26/06

Add additional mz390 pseudo code support:
1) AGO and AIF
2) SETA, SETB, and SETC
3) Add mz390 option PC to generate pseudo code for mz390
4) Add mz390 option TRACEP to trace gen and exec of pseudo code
5) Add mz390 option PCOPT to optimize generated pseudo code:
   a.) PUSHV, ADD 1, STORV optimized to single INC.
   b/) PSUHV, SUB 1, STORV optimized to single DEC.
   c.) CONCAT with null string reduced to single PUSH.
   d.) PUSHA, UCOMP reduced to PUSHA with neg. value
   e.) PUSHA, ADD/SUB/MPY/DIV/COMP?? reduced to 1 op
   f.) Optimize computed AGO using generating GBLA array
         of target line addresses for reuse regardless of whether PC
         option is on or off. Note corresponding GBLC arrray of macro
         labels is also generated for display if TRACEP is on.
For example usage run demo\demom8q1 with NOPC and then PC to see difference in speed. With NOPC it takes over 3 seconds, and with PC it runs under 1 second.   Also see regression tests TESTOPR1 and TESTPC1 with TRACEP generated TRM files. Note TRM files can be very large showing every macro variable value used in every operation of every AIF and SET instruction. TRACEM now generates same source and generated BAL trace with or without option PC so it can be used to isolated where differences occur when running with with or without PC option.

10/04/06

Correct mz390 to return T'&var = 'N' if &var is numeric sdt within quotes.

469

10/05/06

Add new A'symbol operator extension to return 1 if symbol is defined in look-ahead symbol table else 0.

479

10/12/06

Correct &SYSSTYP to return CSECT for sections started with START.

480

10/13/06

Correct error messages for T' operator indicating L' error etc.

483

10/19/06

Correct lz390 to prevent trap and issue error when obj file being read is truncated due to error in az390.

DSH

485

10/26/06

Correct mz390/az390 locking to ensure az390 processing of last generated BAL line is complete before proceeding with mz390 conditional macro code processing. This fixes infrequent situation where mz390 posts new bal line and checks if az390 is waiting before az390 ever has chance to leave previous wait state and process the new bal line.

DSH

486

10/30/06

Upgraded Java SDK and JRE to 1.5.0 update 9. All regression tests will be run on this release starting with z390 v1.1.02c. The only visable change from running same tests on update 7 is an increase of 8 MB in memory usage shown in .ERR files.

DSH

487

11/03/06

Correct mz390 to prevent character string starting with '~' from causing erroneous expression stack error. See updated RT\TEST\TESTASM1.MLC

1.1.02b

09/26/06

Cumulative fixes for v1.1.02

439

09/08/06

Add mz390 pseudo code generator for conditional macro instructions to speed up execution. Option PC is new default option to generate pseudo code during first execution of sstatement for reuse if executed again. Specify NOPC to turn the option off. Option MAXPC(nnn) can be used to change default pseudo code operation cache working set of 50000. Pseudo code generation is only of significant benefit when macro code is repeatedly executed many times. Statistics are provided on total pseudo code operations generated and executed plus the total number of pseudo code lists allocated and reused on least recently used basis if cache size exceeded. These statistics can be used to compare benefit of pseudo code generation and different cache sizes. This initial PTF version only supports AGO code generation but it is enough to see the potential benefit. With PC option an AGO loop executed a million times runs at 2.2 MIPS versus 0.15 MIPS with NOPC option. The dramatic difference is due to overhead of repeated regular expression parsing and hashed symbol table lookups. Additional pseuod code support for AIF, SET, and other statements will be added in future versions.

DSH

461

09/22/06

Add CCGE and CCLE options to RT1 and fix regression test RT\TEST\TESTTIM2 to allow remaining time interval to be same as previously or greater/less to prevent intermittant failures depending on system activity.

1.1.02

09/12/06

Full release with cumulative fixes and enhancements
1. MVS macros now in optional download zip
2, z390 v1.1.02 regression tests now in optional download zip
To run all z390 regression tests, install z390 and the above zips into the z390 install directory with folder names option on, start z390 GUI or command line and then run RT.BAT. It will take a few minutes and will end with list of difference files in descending order by size in the RT\ALL directory. To verify that all the z390 install demos work without the optional zips, run RTDEMO.BAT.

363

07/09/06

Move current MVS macro directory and TEST directory to two separate downloadable zip files on www.z390.org:
1. z390_MVS.ZIP contains MVS 3.8J macros which has the following directory structure:
   MVS    - public domain MVS 3.8J directory
        MACLIB - MVS 3.8J macros in ascii with .MAC
        TEST - test assembly programs using MVS\MACLIB
            SAVE - last verified copy of test files
        DEMO - demo programs using MVS\MACLIB
            SAVE - last verified copy of demo files
        DIF - generated dif files for RTMVS.BAT
2. z390_v1102_RT.ZIP contains the z390 regression test directory for z390 v1.1.02 which has the following structure:
RT       - regression test primary directory
     TEST - source and generated test program files
         SAVE - last verified save of all TEST directory files
   DIF    - generated dif files for TEST versus SAVE
                  by running RTTEST.BAT from z390 root dir.
     ALL   - generated comparison dif files for RTLINK,
                  RTDEMO, RTCICS, RTMVS, and RTTEST
                   by running RT.BAT.

The RTTEST and other regression tests consist of the following:
1. Assemble, link, and execute each z390 regression test to
       generate TEST files BAL, PRN, OBJ, LST, LOG, ERR, etc.
2. Compare each TEST file with corresponding SAVE file to
       generate the DIF comparison files using Windows FC utility.
       (Note LINKLIB RTGENDIR.MLC and RTGENCMP.MLC
       macro text processing programs are used to comparison BAT.)
3. Sort and list the DIF directory in descending order by size of
       of the comparison file to highlight any changes. A few tests
/       such as TESTIM2 using timing will always have differences.

The regression tests using the z390_MVS_MACLIB public domain macro library can be run by using the command RTMVS.BAT from the z390 command line. The RTMVS regression tests include assembly and execution of DEMO program with WTO using the MVS WTO macro with no changes since the form of the WTO used is compatible at the SVC 35 interface level. Note this is not true with most other macros and the z390 system macros must be used at assembly time.

395

08/05/06

Enhance TEST facility as follows:
1. Correct IC and STC to only show 1 byte of storage.
3. Change SS instr. to show up to 16 bytes of to and from fields.
4. Allow up to 100 A hex address break settings. Re-entry address stop to remove it or enter S to clear all breaks.
6. Document that comments on break command show at break.
7. Support use of "EPA" as entry point address reference.
8. Support multiple indirect address references.
9. Compact trace listing for duplicate lines.
See RT\TEST\TESTTST1 regression test.

08/07/06

Publish INSTIME V6 benchmark instruction time report contributed by Melvyn Maltz.

430

09/02/06

Correct az390 to allow low memory references using register 0 base.

431

09/02/06

Add new option LISTUSE with default on to list current USING definitions after each USING and DROP statement. Specify NOLISTUSE to turn this option off. Also fix bugs in DROP dropping wrong labeled using and dropping labeled using by register in error.

432

09/03/06

Correct mz390 to close AREAD or PUNCH open file before switching between AREAD or PUNCH access to the same file so any of the 10 files for each type can be accessed repeatedly in either mode. See TESTPCH1 regression test.

DSH

433

09/03/06

Correct mz390 to always wait for az390 to complete execution when running option ASM. If mz390 aborts due to severe error, force az390 to abort as well and wait for az390 to end after creating PRN with both mz390 and az390 abort errors.

DSH

434

09/04/06

Improve performance of mz390 for large macro expansions:
1) Correct mz390 to check MAXLCL versus MAXSYM for local variable overflow.
2) Save macro label line numbers to reduce need to repeat key index lookups for AGO and AIF statements.
3) Optimize local and global key index routines by eliminating use of random number function and just using string hashcode to derive hash index resulting in 10% elapsed time reduction for large programs.
4) Optimize regular expression parsing patterns to move most frequent patterns to the front and consolidate patterns if possible.
5) See RPI 439 for planned addition of pseudo code generator for faster execution of macro code statements.

DSH

435

09/04/06

Correct mz390 to support default allocation of local macro variable array when subscripted element is set prior to any declaration. See updated RT\TEST\TESTSET1.MLC regression test.

DSH

436

09/04/06

Correct mz390 to correctly parse AREAD and PUNCH operands for end of DSNAME and ignore comments. See updated RT\TEST\TESTPCH3.MLC regression test.

DSH

437

09/06/06

Eliminate TEXT option and always allow AREAD text input of any length from optional AREAD text files. Inline AREAD input strings may also be longer than 71 characters if the starting inline data input line is continued with non-blank character in position 72. Note PUNCH output text file records can be of any length. Also correct mz390 bug to check for macro not found previously to avoid erroneous error 119 macro index table exceeded error.

DSH

438

09/07/06

Add az390 initial very limited support for DS/DC bit lengths if and only if the bit length is a multiple of 8. See RPI 417 pending for addition of full bit length support.

440

09/08/06

Route all MNOTE's to ERR file as well as BAL and PRN files. Correct ez390 and sz390 to honor NOCON option.

441

09/08/06

Update pz390 as follows:
1) Correct 0C7 on TP command with bad sign and length 1-8.
2) Speed up TRT by ending loop at first hit.
3) Add move string instruction MVST.
See updated RT\TEST\TESTINS2.MLC.

442

09/08/06

Correct az390 calculation of symbol value based on * location counter in DSECT during first pass which can cause mz390 to fetch bad value even though az390 corrects it on second pass. See updated RT\TEST\TESTSYM1.MLC.

DSH

443

09/10/06

Add new benchmark test macro text processing program BMK\BMKTIME.MLC which can be used to measure the elapsed time of any process run between calls to BMKTIME which records starting time on first call and ending time and elapsed time on second call with SYSPARM set to text file to contain timing statistics. Run BMK\BMKTIME.BAT for example timing of DEMO\DEMOM8Q1.MLC showing 40k macro instructions per second versus 35k on previous release.

DSH

1.1.01e

09/02/06

PTF cumulative fixes for v1.1.01

423

08/31/06

Prevent recursive abort error when az390 attempts to close down by catching internal exception on separate thread. Also add same exception handling in ez390, sz390, and gu390_screen threads.

424

08/31/06

Correct az390 to correctly handle invalid constants in E, D, F, H, and L type DC statements and issue appropriate error.

425

09/01/06

Generate mz390 statistics just before END statement if BAL and STATS option specified so the statistics show up on both BAL and PRN files. Force listing of all file cross references with error count > 0 at the end of both PRN and ERR file for easy reference. Show the total number of errors on each file reference. Correct ERR file to set default .ERR suffix when not specified. Add file and line cross reference after bal line number on all error messages (not available when az390 is run separately from mz390).

426

09/01/06

If the mz390 macro expansion had hard errors, suppress multiple passes in az390 attempting to resolve forward references and go directly to last pass to generate PRN listing to save time.

427

09/01/06

Correct mz390 to issue error if option NOASM is specified and attempt to access valid ordinary symbol name is made in AIF expression.

428

09/01/06

Correct sz390 to ignore high bit in 8 byte address stop address.

1.1.01d

08/30/06

Cumulative PTF fixes for v1.1.01

410

08/12/06

Correct mz390 to issue error for incorrect DSNAME= or DDNAME= extension on PUNCH or AREAD statements. See new LINKLIB\RTGENBAT.MLC. Correct mz390 to substitute macro variables on PUNCH statement on BAL as well as PCH. Correct AREAD to return 1 space for lines with all spaces or cr,lf only. A 0 length string from AREAD indicates end of file. Add AREAD and PUNCH I/O counts to mz390 stats. See new regression test directory processing programs LINKLIB\RTGENDIR.MLC and LINKLIB\RTGENCMP.MLC used in RT batch commands to generated BAT files for comparing files in 2 directories. If MNOTE level 16 or abort is issued, return it as mz390 return code instead of 0 which is returned for mnote levels 0-15 for az390 to list and handle..

DSH

411

08/14/06

Improve performance of mz390 as follows:
1. Reducing string concatenation wherever possible to reduce string garbage collection overhead.
2. Replace while loops to init arrays with Array.fill function.
3. Replace while loops to copy arrays with System.arraycopy.

412

08/14/06

Correct mz390 to reset abort flag during loading of macros in order to display multiple errors found during loading such as multiple duplicate macro labels. Eliminate duplicate mz390I pgm and options msgs in z390 GUI log. Correct missing space on error message 72.

414

08/14/06

Correct mz390 to recognize ERR(nnn) override for maximum errors. If nnn is 0, no limit is set.

415

08/14/06

Change mz390 to automatically call az390 when option ASM (renamed from option MFC) is on. This enables mz390 to share the az390 symbol table during first pass for AIF expressions including ordinary symbols such as calculated length of DSECT's. The ASM, ASML, and ASMLG commands have all been updated to eliminate separate az390 step by using mz390 with new default ASM and NOBAL which suppresses creation of BAL file. The MAC command assumes NOASM and BAL to enable using the macro processor as a powerful macro based text editor with no mainframe ASM dependencies. The AZ390.BAT command can still be used to run az390 separately after first creating BAL file using MAC with BAL option which may be used in testing. See RT\TEST\TESTSYM1 for macro code test of ordinary symbol DSECT length in AIF.

416

08/14/06

Correct az390 loop on invalid DS/DC length expression.

419

08/20/06

Correct mz390 T', L', and D' operators to correctly parse SETC variable text to extract first ordinary symbol as operand for operator. The symbol may have labeled using prefix and may have trailing expression operator such as T'&PARM where &PARM is BLK.FLD+5. See updated RT\TEST\TESTSYM1 regression test.

420

08/21/06

Allow support for multiple AREAD and PUNCH files using ID=n where n is 0 to 9. Also support DSN= as alias for DSNAME= in AREAD and PUNCH extended options, and add documentation on extensions to User Guide. See RT\TEST\TESTPCH3 new regression test to copy and merge 2 text files.

421

08/24/06

Correct support for &var.nn'...' to concatenate duplication string. See updated RT\TEST\TESTOPR1 regression test.

422

08/30/06

Correct incorrect comparison between two strings padded with blanks to the same length but with unequal EBCDIC characters > 128.

PTF cumulative fixes for v1.1.01

390

08/04/06

Remove DSH2 change to FPCONVRT and change DSH3 to use IC RO versus IC R1 and remove the extra LR R0,R1. Superseded by RPI 405. RTLINK.BAT.

391

08/04/06

Change FPCONMFC to change trailing null bytes in decimal output area to spaces. See RTLINK.BAT.

DSH

393

08/05/06

Issue SF05 program check if wait svc issued with wait count higher than total entries in the ECB list or if ecb_list exceeds max of 16.

394

08/05/06

Correct GETMAIN macro to issue warning and ignore any SP= subpool specified. See RPI 244 and RPI 248 pending request for subpool support. All pools are combined currently so PURGE of subpool is not currently supported.

396

08/06/06

Change TESTTIM2 to expand STIMER REAL test to allow 15 seconds for task to get 2 seconds of cpu time. It was set at 2.5 seconds and caused U101 abend when background Windows task caused cpu time to be shared thus requiring over 4 seconds to get 2.

397

08/06/06

Fix pz390 to issue S0C5 on all memory accesses beyond current memory allocation based on MEM(mb) setting. Previously it was only checking instruction address resulting in exception handler in ez390 trapping exception from pz390 running on separate thread causing synchronization problem with log output when running under z390 GUI interface. Fix also applied to ez390 exception handler to try and correct synchronization problem when similar unexpected exceptions occurs in pz390.

ABE

398

08/06/06

Fix pz390 divide D and DR instructions to avoid truncating divisor prior to divide. Also speed up D, DR, SLDL, SLDA, SRDL, and SRDA by using long shift and or versus byte buffer int stores and long fetch. See updated TESTINS2 with expanded D and DR tests.

401

08/07/06

Fix mz390 to expand arrays as required when multiple store values exceed current allocated size. Previously only declaration or initial store index could automatically force expansion. Also display separate statistics for global seta, setb, and setc cells. See TESTSET2.

402

08/07/06

Change mz390 to report count of MNOTE warnings with level 1-4.

403

08/07/06

Change az390 to correctly restore original opcode usage when original opcode name is set to previously defined alternate name for the original opcode. See updated TESTSYN2.

404

08/07/06

405

08/07/06

Fix mz390 to correct error handling O' operator to test opcode and replace current FPCONVRT.MAC with updated version contributed by David Bond that has previous fixes plus new support for IEEE-754R decimal floating point ED, DD, and LD (MIN) and (MAX) values if the assembler supports z9-bc instructions including SRNMT tested via O'SRNMT. See RPI's 406-407 for additional z390 support pending for z9-bc instructions and IEEE-754R decimal floating point. See IBM General Decimal Arithmetic for overview. See TESTOPR1 for updated O' tests.

408

08/09/06

Fix gz390 GUAM graphical user access method to expand the default screen size by a few pixels to prevent cutting off part of border characters on screen. Also fix trap in gz390 when running DEMOGUI5 which tries to resize graph view. See RPI 137 pending to complete addition of graphics support when time permits.

409

08/10/06

Optimize speed of mz390 starting with optimization of find_key_index to avoid extra string concatenation of type by passing char type separately. Also skip string compares if not target type. At least 10% speed improvement observed on 2 second macro expansion of TESTINS2.

07/17/06

Add new z390 open source directory LINKLIB with the following programs:
1.) FPCONVRT.MAC - floating point conversion routine generation macro contributed by David Bond with Tachyon Software. The original source code can be downloaded here: ftp.tachyonsoft.com/tachyon/fpconvrt.zip. Note the program can be assembled and executed using z390 without any changes. However, 4 single line changes were required to FPCONVRT.MAC in order to successfully run the test programs below with identical results compared to z390 svc calls. The changes are tagged with DSH1-DSH4.
2. FPCCONVRT.MLC - 3 line macro call program to assemble FPCONVRT.MAC to FPCONVRT.OBJ format for static linking using the ARCHLVL set by new ARCHLVL macro.
3. ARCHLVL.MAC - macro to set desired OS or z/OS architecture level global variable &ARCHLVL and &ARCHSFX 32 or 64 bit register suffix of null or "G". All of these programs have been successfully tested with ARCHLVL=2 for OS 32 bit linkage and also ARCHLVL=5 for z/OS 64 bit register linkage plus use of z9-101 instructions. Note the current setting for this macro is ARCHLVL=5 for testing the 64 bit support. However, you can use ARCHLVL=2 for typical 32 bit application testing on the PC..
4. FPCONMFC.MLC - interface program to map z390 CTD and CFD macro calls into corresponding calls to FPCONVRT when the LINKAGE=MF option is used. The CTD and CFD macros default to using z390 svc 170 and 171 for maximum speed. The LINKAGE=MF option generates calls to FPCONMFC and in turn FPCONVRT for source code compatibility with the mainframe. Note this program also uses ARCHLVL to determine correct linkage for FPCONVRT calls.
5. TESTFPC1.MLC is a regression test of CTD, CFD, FPCONMFC, and FPCONVRT for all floating point types plus 128 bit integers using both SVC and MF linkage. Note the default LINKAGE=SVC is significantly faster for testing on PC. After testing you can use the MF calls to FPCONVRT when required to port applications to the mainframe.
6. TESTFPC2.MLC is regression test of all 6 floating point (MAX) and (MIN) value constant conversions to and from decimal values.
7. CVTTOHEX.MLC is a callable routine to convert any number of specified bytes to hex for use in displays. See TESTFPC1 for example use.
8. See RTLINK.BAT for assembly, link, and execution of test programs in LINKLIB.

3) ZSTREQU.CPY - copybook to define symbols E, EQ, NE, etc.
The ASMMSP copybook in the MAC directory must be included in each program using using the ZSTRMAC structured macros. The ZSTRMAC macros are public domain and are derived from macros on CBT overflow tape 178 which were developed in 1974. See ACM SIGPLAN article date February 1975. The macros were contributed to the SHARE SPLA library in the late 1970's. The macros have been renamed and updated for compatibility with the IBM toolkit structured macros based on this SHARE presentation by Edward Jaffe. Individual IF test operands may be in (...) and compound tests may be connected with AND or OR. The test operand sequence is:
1) compare instruction opcode
2) first compare instruction operand
3) BC compare type (see EQU symbols in ZSTREQU.CPY)
4) second compare instruction operand

1.0.14a

04/19/06

1. RPI 241 - correct mz390 to ignore errors on &variable substitution
on BAL output and let az390 flag any errors. This allows invalid
variables in comments or data to not generate errors.

2. RPI 283 - correct FREEMAIN macro to ignore SP= and correct
other MNOTE error messages. Note SP= support will be required
only if the test application uses subpool purge. See pending RPI248.

3. RPI 284 - add the following maximum table limit optional overrides:
a. MAXCALL(50) - maximum nested macro calls
b. MAXESD(1000) - maximum external symbol definitions
c. MAXFILE(1000) - maximum macro files loaded
d. MAXGBL(50000) - maximum global macro variables and cells
e. MAXLCL(50000) - maximum local macro variables and cells
f. MAXLINE(200000) - maximum source MLC, MAC, and CPY lines loaded
g. MAXPARM(10000) - maximum positional and key word parameters
h. MAXRLD(10000) - maximum relocatable definitions
i. MAXSYM(50000) - maximum ordinary symbols and macro labels
j. Previous MAXFILE(50) for max file size renamed to MAXSIZE(50) mb
These limits are targeted to handle 99% of assembler programs
without overcommiting memory for the few very large programs that
will require one or more overrides. RPI's to adjust defaults welcome.

01/14/06

Add OPSYN support and BMK\INSTTIME.MLC instruction timing analysis by Melvyn Maltz.

RPI 107 - Improve maintainability of the z390 java source code by splitting sources into smaller classes by function:
1) Move z390 instruction processing code out of ez390 to separate class pz390.
2) Also changed ez390 to run pz390 on separate thread for about 10%-15% performance improvement across the board.
RPI 148 - Add &SYSMAC system variable. See TESTSYS1.
RPI 149 - Fix bug when redefining instruction with inline macro with MFC option. See TESTMAC3 which redefines B and BRC 15.
RPI 150 - Add OPSYN support. See TESTSYN1 regression test.
RPI 151 - Add user option to define first level svc handler by setting new svc PSW mask to x'FF' and new address. When mask is set, the old svc PSW is store and control is transferred to the new svc PSW address. To execute native z390 svcs, the handler must reset new svc PSW mask to X'00'.. LPSW instruction enabled as part of this RPI to allow handler to exit via LPSW SVC_OLD instruction without using any registers. WTO macro changed to use BRAS versus BAL so WTO can be used in handler without base register required. See regression test TESTSVC1 which uses this option to map user svc 201 into a WTO svc 35. Note it also checks for the svc 3 exit and does it in native mode so user does not have to turn off handler prior to normal exit.
RPI 153 - Remove duplicate label from WTO MF=L option
RPI 154 - Add new performance analysis program INSTTIME.MLC contributed by Melvin Maltz. Run BMK\INSTTIME.BAT to generate new BMK\INSTTIME.OUT report file.

RPI 155 - Upgraded to Sun Microsystems J2RE version 1.5.0.06 for build and regression testing.
RPI 156 - Correct SNAP macro to support PDATA parm value of DCB instead of previous TIOT to show open DCB's with DDNAME and DSNAME. This makes SNAP more consistent with TEST subcommand D.
RPI 157 - Correct az390 to flag extra operands at end of expressions. See updated regression tests TESTDC1, TESTASC1, and TESTERR2.
RPI 158 - Correct LLIHH, LLIHL, LLILH, and LLILL load logical instructions to clear remaining bits in 64 bit register. See updated TESTINS2 and other regression tests which used LL type instructions instead of II type instructions in error. Change usage of LLILH and LLILL to IILH and IIll in SNAP macro caught by this fix. See regression test TESTDMP4.
RPI 159 - Correct az390 regular expression parser to return = as token in order to detect error when absolute value operand is incorrectly defined as literal. See updated regression test TESTERR2.
RPI 160 - Correct LLGT instruction which was loading from 4 bytes beyond D2(B2). See TESTINS2 correction.
RPI 161 - Correct az390 RXY to allow d2(,b2) like RX instructions by eliminating duplicate code which did not get fixed in RPI 3. See updated TESTINS1 regression test.
RPI 162 - Correct GETMAIN macro to correctly support new LV=nnnK or LV=nnnM option. Correct mz390 to correctly return numeric portion of string followed by non-numerics (i.e. &LEN SETA &LV should return 1 not 0 for &LV=1K. See new TESTMEM2 regression test.
RPI 163 - Update all macros to suppress register loads for same register.
RPI 164 - Correct az390 to allow locally defined ordinary symbol to resolve EXTRN reference so that CALL and SUBENTRY will resolve to local static call without duplicate label error. See new regression test TESTCAL1. See regression tests TESTCAL1 and TESTCAL2. Existing regression tests for external static calls and dynamic calls are TESTEXT2 and TESTLNK1.
RPI 165 - Add USAGE statement references to az390 XREF list.
RPI 166 - Fix az390 to correctly generate RSY and SIY type instructions such as SRAG and TMY with explicit base and displacement. See updated TESTINS2 for SRAG and TMY with explicit base register.
RPI 167 - Issue error message for any source MLC statement which is continued due to non-blank character in position 72 and the following line has non-blank text before position 16. Fix continuation errors in XCTL, ESPIE, LINK, LOAD, DELETE, and SNAP.
RPI 168 - Correct directory null pointer exception when using path with . for current directory.
RPI 169 - Correct az390, lz390, and ez390 to always use BAL, OBJ, and 390 as primary input extension ignoring any user override for mz390 primary input extension. Correct mz390 error message 39 to insert space between text and missing file name.
RPI 170 - Allow fifth positional parameter 'S' on READ or WRITE. Any other value is an error since this parm is only used or RECFM=U which is not supported, and DCBBLKSI is always used as length. See TESTDCB9.
RPI 171 - Correct mz390 and az390 expression parser handling of unary minus in complex expressions and allow multiple +- unary operators in succession. See TESTSET1 and TESTASM`1.

RPI 127 - Allow user specified file type overrides on filename parm and directory lists using path\*.type. See new regression test TESTMCR1.ASM which uses macros with MCR suffix.
RPI 130 - Add the following mz390 system variables:
&SYSASM = z390
&SYSCLOCK = YYYY-MM-DD HH:MM:SS.mmmmmm
&SYSDATC = YYYYMMDD year, month, day
&SYSDATE = MM/DD/YY month, day, year within cc
&SYSECT = current section
&SYSLOC = current LOCTR or last section
&SYSNEST = macro call nesting level
&SYSPARM = mz390 user option sysparm(xxxxx)
&SYSTEM_ID = operating system and version
&SYSTEM_JAVA - Java vendor and version
&SYSTIME = HH.MM time of day
&SYSVER.= version of z390 macro assembler
See TESTSYS1 regression test for all of above. Note when option NOTIMING is specified the same time and date is always returned - 01/02/05 33:44:55.567000.
RPI 133 - Add MAXFILE option with default of 10 MB maximum size for any output file from mz390, az390, lz390, or ez390. You can override with MAXFILE(nn) in MB.

RPI 144 - Correct precedence in mz390 expression parser to make + or - higher than logical compare
RPI 145 - Correct precedence in mz390 expression parser to prevent error when K' operator appears as only token in substring starting offset expression ot when two K' operators appear in succession.
RPI 146 - Add new mainframe compatibility option for mz390 called MFC as default which prevents instruction opcodes from being treated as macros unless previously defined via inline macro. This option for mz390 replaces option SYM to request ordinary symbol label type and length support during macro processing. To turn off both opcode checking and symbol support, specify NOMFC. Also new statistic added showing unique instruction count.
RPI 147 - For mainframe compatibility correct NOT for SETB type variables to return 0 or 1 rather than complement (ie -1 for NOT 1).

1.0.08

12/15/05

Add GUI graphical user interface with MCS console view for WTO and WTOR, TN3270 view for TPUT and TGET in edit and FULLSCR 3270 data stream mode, and graphic display view.

RPI 47 - Add GUI option to ez390 which enables GUI dialog window with 3 different view options:
1) MCS console view for WTO and WTOR messages. Run DEMOGUI1 and DEMOGUI2 with GUI option for demo.
2) TN3270 view for TPUT and TGET with EDIT and FULLSCR options. Run DEMOGUI3 and DEMOGUI4 with GUI option for demo (FULLSCR support is not done yet and uses EDIT mode for now - see RPI 136).
3) GRAPH view support for graphics output generated using GUI macro graphics options. Run DEMOGUI5 with GUI option for demo (Graphics support not done yet so demo just shows title and text output on graphic display for now - see RPI 137). Note this demo also outputs MCS and TN3270 messages so you can view all 3 displays via menu. See new z390 GUI Graphical User Interface Guide for supported macro interfaces.
RPI 105 - Research issue with maximum memory that can be allocated via MEM(mb) option on a system. The J2RE virtual machine option -Xmx can be used to set maximum memory available. See FAQ for more information and example.
RPI 108 - Improve performance of additional compute intensive instructions:
1) BC no branch reduced from 519 to 343 NS by skipping RX target address fetch if no branch to be taken.
2) AP and all PD speedup by using Long versus BigInteger when values within range.
3) MVCL and MVCLE speedup by using block copy and fill.
4) MVZ, MVN, OC, NC, XC all speeded up by replacing byte loop with Long, Int, Short, byte loops.
5)All instructions speedup by replacing mem.get(...) buffered fetch with mem_byte[...] direct byte array fetch, also mem.put() and reg.get() and reg.put().
See Benchmark Testing page for more results.
RPI 109 - Fix packed decimal instructions to issue 0C7 versus 0C5 under certain error conditions. Note 0C5 is the default abend for any error not recognized or specifically handled by ez390.
RPI 110 - Fix SNAP macro bug setting wrong bit for STORAGE request. Update SNAP svc to correctly format TIOT entries for closed files showing DCBOFLG open bit off. Add check for register conflict. See TESTDCBD for regression test including SNAP of open and closed DCB's.
RPI 111 - Fix LOAD support to strip leading and trailing blanks in DSNAME field. This fix causes a LOAD of a file name and suffix matching any previously loaded file or 390 program to be treated as identical resulting in CDE use count being incremended and same address being returned in register 0. Register 1 is set to length in double words or 390 or bytes for any other file. See updated TESTLOD2 regression test.
RPI 112 - Fix I/O macros:
1) POINT - add missing AGO
2) CLOSE - check for invalid DCB RX form (reg) vs ((reg))
3) Correct EZ390E error 90 for I/O error on READ/WRITE
RPI 113 - Fix all z390 file handling to correctly handle files with drive letter and colon path but no file separator in the path.
RPI 114 - Fix WTO and WTOR to use more unique labels to avoid duplicating user labels.
RPI 115 - Fix mz390 and az390 continuation processing to correctly handle comma and space appearing within literal which is continued (previous truncating line after comma). See TESTDCBA for example.
RPI 116 - Issue error if no END statement found in az390.
RPI 117 - Fix GETMAIN and FREEMAIN macros to allow 31 bit length for LV=, support nnnK = nnn * 1<<10 and nnnM = nnn * (1<<20) short form extensions, issue error for missing LV=, and correct spelling errors.
RPI 118 - Fix LINK, LOAD, XCTL, and DELETE macros to use SR verus LA, check for register conflicts. Correct OI for VL bit setting in LINK, XCTL, and CALL. Remove BALR, USING and add optional register restore in XCTL.
RPI 119 - Add floating point and hex options to EQUREGS macro. See TESTSET1.MLC for new tests of multiple value sets required for EQUREGS update. See TESTEQU1 regression test for use of REGS=GPR/FPR and TYPE=DEC/HEX options.
RPI 120 - Fix assembly of SRP instruction when using explicit d2(b2) operand (was dropping base). See updated TESTINS2 regression test.
RPI 121 - Change TEST subcommand Q to abort rather than continue execution. Fix G xxx where xxx is invalid to just issue error message and return to prompt instead of running.
RPI 122 - Add support for following az390 statements:
1) AMODE, RMODE - ignored (use linker options)
2) AEJECT, ASPACE, CSPACE, EJECT, PRINT, SPACE
RPI 123 - Correct multiple directory search logic to correctly handle multiple directories in mz390, lz390, and ez390.
RPI 124 - Truncate trailing blanks and sequence # beyond 72 during loading of mz390 and az390 source code.
RPI 125 - Add support for setting multiple SET values in array by adding multiple expressions separated by commas, See updated TESTSET1 regression test.
RPI 126 - Ignore duplicate macro variable array declarations and use the first declaration to set fixed maximum array size. This is a current restriction compared to mainframe which allows arrays to grow dynamically.

11/20/05

Add additional benchmark timing support and debugging aides

RPI 8 2 Document instruction timing results on website and look for ways to speed-up frequently used instructions. Performance RPI's will be accepted including requests to add new svcs and/or opcodes to "microcode" frequently used instructions loops that need more speed. See instruction timming benchmark test program BMKINS1.MLC with results posted on Benchmark page of www.z390.org. The first performance improvement completed was replacement of MVC byte loop with single function move or fill function resulting in reduction of 256 byte move from 41 microseconds to 880 nanoseconds.
RPI 92 Correct instruction trace format errors in test versus normal instruction trace due to type index off by 1 causing those instructions such as CVDG at beginning of new type to be formatted as previous type. See BMKINS1.MLC for usage of CVDG.
RPI 93 Correct SNAP svc x'51' which was incorrectly using ending storage address as length instead of ending address. See updated TESTDMP4.MLC.
RPI 94 Add new extended TIME NS macro option to return high resolution nano-second timer value useful for interval measurements. See BMKINS1 for example usage.
RPI 95 Update LOAD macro with DDNAME= and DSNAME= support identical to LINK macro. Add new XCTL macro using svc 7. Add DDNAME= and DSNAME= conflict check on LINK, LOAD, XCTL, and DCB. See TESTLNK1 for LINK tests. See TESTLOD1 for LOAD tests, and see TESTXCL1-3 for XCTL test. See TESTERR3 for conflict error tests.
RPI 96 Add validity checking for DCB LRECL, BLKSIZE and RECFM. Accept both OPEN file and OPEN (reg) as extensions for input. Correct missing AGO in POINT macro. See TESTERR3.
RPI 98 Add new DUMP and ASCII mode to the GUI option menu. Also correct failure observed on first batch command after changing menu options due to not correctly flushing queues between end of previous batch initiator process and restart. Manual test of batch commands with DUMP and ASCII options tested.
RPI 99 Correct mz390 AIF expression parser bug when substring expression appears after logical operator in complex expression. See TESTERR3 tests using complex AIF testsin DCB macro.
RPI 100 When running in TEST mode, issue ABEND dump if requested before returning to test prompt. Also reformat ABEND dump to include system/user type ABEND codes with PSW and current instruction. If dump requested by caller or system dump option then also display GPR and FPR registers, TIOT DCB's if any, CDE program entries, and dump of each program. See TESTDMP1 to TESTDMP4 for examples of ABEND and SNAP output.
RPI 101 Correct erroneous read past end of file error due to not resetting TIOT DCB rba pointer on reopen of existing entry. See new TESTDCBD and TESTDCBE (same test run in ASCII mode) regression test program provided by MM. Note ASCII mode does not translate RT or VT input so all the hex values including EBCDIC characters are retained as is in input records.
RPI 102 Add additional LOAD and DELETE macro support: Return 390 file length as double word count in R1 for OS compatibility. If DDNAME or DSNAME point to file spec with path, file name, and suffix other than 390 then set R0 to load point for file content and set R1 to total file length in bytes. Allow DDNAME or DSNAME to replace EP or EPLOC. See TESTLOD2 regression test loading 2 text files.
RPI 106 Correct following instruction bugs: SPM and IPM not putting mask in correct position (MM) NR, OR, and XR condition code not set (MM) PR restoring R15 incorrectly (IS) See TESTINS2, TESTFP1, AND ESPIE macro updated regression tests.

1.0.06

11/14/05

Enhance ASCII mode support including PKA and UNPKA instructions. Enhance CMDPROC to support multiple tasks. Add DUMP option, SNAP macro, and TEST sub-commands to display GPR and FPR registers, CDE program info, TIOT DCB info, and memory statistics. Add XLATE translation macro.

1. RPI 85 - Issue errors for DC F and H type signed field values that exceed range for length specified. See TESTERR2.

2. RPI 86 - Add following additional TEST sub-commands:

D - display DCB file information
F - display floating point registers
M - display memory totals
P - display program information
R - display general registers
See TESTTST1 updated regression test.

3. RPI 87 - Correct erroneous error 102 on ORG statement occurring whenever last expression calc prior to ORG resulted in absolute value rather than RX type symbol in same csect. See TESTASM1.

4. RPI 88 - Correct error in OPEN and CLOSE macro for DCB register parm. Add DCB validity checking at execution time. Note this RPI requires reassembly of all DCB's with new validation field named DCBID in DCB and DCBD macros. See new TESTERR6 regression test.

6. RPI 89 - Add option for LOAD and LINK to use extended keyword DDNAME= or DSNAME= defining program file path list or specific file via environment variable or program constant with file specification. If directory path list is specified, then EP or EPLOC is required to define the program name. If a file specification for 390 program is specified, then it overrides any EP or EPLOC name. DSNAME overrides DDNAME. See TESTLNK1 for example regression test.

7. RPI 90 - Correct v1.0.05 regression error causing trap when single character labels B, C, or X are used due to erroneous test of 2nd character for self defining term quote. See TESTASM1 updated regression test.

8. RPI 91 - Add support for XLATE macro via svc x'67' to translate between ASCII and EBCDIC. See regression test TESTXLT1

1.0.05a

5. RPI 84 - allow comments on copy statements

1.0.05

11/04/05

Add TIME macro SVC 11 extensions for CLOCK type STCK, STCKE, and JAVA different epoch clock time formats

1. RPI 58 - Correct STCK and STCKE to be mainframe OS time compatible. STCK stores double word with bit 51 corresponding to microseconds from January 1, 1900. STCKE stores 16 bytes with bit 59 corresponding to microseconds from January 1, 1900. See TESTTIM1.MLC update.

2. RPI 61 - Remove duplicate CR,LF from RECFM=FT and VT output format in ASCII mode. No duplicates found, see RPI66 and regression test TESTDCBC.

3. RPI 62 - Remove extra space from command recall in TEST mode. Manual GUI test.

4. RPI 63 - Recognize x'1A' as end of file marker on DCB RECFM=FT or VT read and branch to EODAD. Note you can use superzap (www.superzap.net) to view and verify hex codes in any Windows file such as the input and output test file in this regression test. I also used superzap to add the hex x'1a' code to test file with the command sequence OPEN, DUMP, SFL (set file length), and REP command. See TESTEOF1.MLC.

5. RPI 64 - Correct error handling for invalid DCBDSNAM field with or without TEST mode. The DCB synad handling routine now issues error message followed by S013 abend for consistent handling with or without TEST active. See TESTERR4.MLC.

6. RPI 65 - Correct BALR, BASR, and BASSM to branch when R1 = R2. See TESTINS2.MLC update.

7. RPI 66 - Correct ASCII mode padding of RECFM=FT records to use ASCII X'20' versus EBCDIC X'40'. This should also fix RPI61. See TESTDCBC.MLC run in ASCII mode.

8. RPI 67 - Change TEST mode command G, T, or Z opcode to always execute at least 1 instruction before breaking on next matching opcode. Breaking on BCT to itself now executes once per G, T, or Z BCT. Manual test.

9. RPI 68 - Add 3 SVC type extended options to the current IBM compatible TIME macro:

1. CLOCKTYPE=STCK store double word with bit 51 = microseconds from Jan. 1, 1900 IBM Epoch.
2. CLOCKTYPE=STCKE store 2 double words with bit 59 = microseconds from Jan 1, 1900 IBM Epoch.
3. CLOCKTYPE=JAVA store double word with bit 63 = microseconds from Jan 1. 1970 Java Epoch.
See TESTTIM1.MLC update.

10. RPI 69 - Change ED and EDMK to map X'40' to ASCII space X'20' when running in ASCII mode. Note the following ASCII characters cannot appear as characters in ASCII mode due to conflicts with predefined special codes:

1. ASCII @ (X'40')
2. ASCII space (X'20')
3. ASCII ! (X'21')
4. ASCII " (X'22')
The above codes can be moved into edited fields after ED/EDMK. See TESTASC3.MLC regression test which is run in ASCII mode.

11. RPI 70 - After install of z390 v1.0.04 on Win/2000 with J2RE 1.5.0_5, system failure with error - java.lang.UnsupportedClassVersionError: mz390 (Unsupported major.minor version 49.0). Planned fix is to build 1.0.05 on XP update 4 instead of XP update 5 since that fixed win/2000 problem seen back in v1.0.00. Manual test on Windows/2000.

12. RPI 71 - ez390 loader incorrectly relocating AL3(*) type address constant. See TESTINS2.MLC update.
