See the above Github link for summary of changes and download links for z390 to run on Windows, Linux, and Mac OS. The z390 assembler now assembles all 2385 opcodes defined in the latest Principles of Operations manual, and the z390 emulator executes most of the problem state instructions including HFP, BFP, DFP floating point, and newer instructions such as CDPT, CXPT, CZDT, and CZXT.

The above z390 release directory zip includes z390.jar, and can be copied to any local directory. The only other requirement is Java runtime 8+ to assemble, link, and execute both assembler and COBOL programs. See bat and bash directories to run RUNASMDEMOS and RUNCBLDEMOS commands which include display “Hello World” programs and other demos. The z390 release includes both a command line interface and a Graphical User Interface (GUI). The GUI can be started using the bat\z390.bat or bash/z390 command. Also included is a sort merge utility which has demo command you can run bat\RUNSORT.BAT for Windows or bash/RUNSORT for Linux or Mac OS. The sort demo will sort a million records in a few seconds.
To rebuild the z390.jar from java sources, download the z390 release source code which includes java sources in src directory:
https://github.com/z390development/z390/archive/refs/tags/v1.8.0.zip
The above source code zip includes commands BUILD.BAT and build.sh which will rebuild z390.jar and run regression tests. These build commands require Java Development Kit JDK 8+ and java runtime which can be downloaded here:
