Welcome to the z390 portable mainframe macro assembler and emulator project web site.
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 CICS SEND and RECEIVE commands
      • Sequential and random file access using EBCDIC or ASCII
    • Macro assembler mz390 is compatible with HLASM including:
      • All source code for programs and macros in ASCII
      • Structured macros – IF, ELSEIF, ENDIF, DO, ENDDO

    • Linker lz390 supports:
      • Supports standard OBJ relocatable object files and optional OBJHEX relocatible object file format which is in readable ASCII text with support for 31 bit sections.
      • Builds 390 relocatible load modules with AMODE 24 or 31 bit options
      • Optional LKD command files with INCLUDE, ENTRY, ALIAS, and NAME commands
      • Option AUTOLINK for automatic search for external references
    • Emulator ez390 supports:
      • problem state instructions including z9, z10, and ASSIST opcodes  
      • 32 & 64 bit register instructions
      • 24 and 31 bit addressing supporting memory up to host system limit
      • Supports HFP, BFP, and DFP 32, 64, 128 floating point
      • Interactive TEST facility for debugging
      • Extensive TRACE facility for debugging
      • Support for the above MVS compatible macros provided via z390 svc calls
