z390 is a Java J2SE Open Source tool with the following major features:
    • Use z390 graphical user interface or command line interface
    • Use simple commands to assemble, link, and execute programs
      • Type  ASMLG demo\DEMO to assemble and execute demo.mlc
    • z390 program user interfaces include
      • MCS console interface WTO and WTOR
      • TN3270 full screen interface using:
        • TGET and TPUT macro interface
        • EXEC CICSSEND and RECEIVE commands
      • Sequential and random file access using EBCDIC or ASCII
