MVS and VM Goodies

Tapes are the standard way to exchange files, utilities and information between mainframes. Some mainframe shops are now connected thru the HNET Bitnet II international dial-up network. I also noticed that recently the industry is moving towards a new fad called the "World Wide Web", which is why I now make this colleciton of tools and utiliteis available on Github in this crazy new world of the Internet!

For more information on HNET/Bitnet II, chck out here: http://moshix.dynu.net

This repository includes some very useful utilities for people working with MVS, z/OS, VM/SP and z/VM on real mainframes or emulated ones. It also includes some operating systems or extensions for operating systems. Most of the topics covered by these programs are covered in my youtube mainframe channel here: https://www.youtube.com/channel/UCR1ajTWGiUtiAv8X-hpBY7w

Here are some of the programs and tools included in this repo:

  1. recv390 is a receive command for Linux or Windows. It extracts XMIT files. recv390 is by James Morrison. I made some fixes and small enhancements to the program. Compile simply with gcc -o recv90 recv390.c.

  2. SYCPLK.ccdk is a 3390-3 volume (SYSCPK) which includes about 10 or 12 compilers for the mainframe, including:

  • PLI F compiler
  • Cobol compiler from the 60s
  • RPG compiler
  • PL/360 compiler
  • Pascal compiler
  • the amazing ASSIST assembler
  • Simula compiler
  • Basic
  • and tons more!

Simply mount the volume on your system, add it to the VTLST00 member as private, and then extend your JES2 to use the included SYS2.PROCLIB on SYSCPK. This proclib has procedures for all the included compilers. The run-time libraries, like SYSC.PLILIB are of course included in the volume.

I tested in on everything from MVS 3.8 to OS390 all the way to z/OS 1.13 and it works beautifully. There is also a version of this volume on 3350 disk image, but OS390 and up don't have support for such old disks anymore. Copying stuff over to a 3390 disk isn't trivial because of the blocking required by certain compiler libraries. In short, there is a need for this volume.

  1. sort.jcl is a sort job which stresses a Tk4 MVS 3.8 by creating millions of random records and then using IBM Sort to sort them.

  2. The amazing standalone operating system for S/360 from Prof Madnick's seminal book on operating system. I also include the assembly output.

  3. My .vimrc file for VIM. It color highlights correctly JCl and assembler for S/370.

  4. NJE config files

  5. The usefuljcl/ directory contains very useful JCL jobs which you will use on adaily basis as a MVS or z/OS SYSPROG

  6. a calculator for ideal blocksize given a DASD type and a logical record length, written by me in Go language. It's called blocksize.go and I also inlude a Linux 64bit binary

  7. the PC370 source code for the simply amazing S370 assembler which runs in MS-DOS.

  8. Lots of JCL and source code files which I use in my moshix mainframe channel vidoes

  9. Some JCL for Cobol and VSAM on z/OS

  10. My REXX programs for both z/OS and MVS 3.8 to get information from the operating system, such as online users, IPL time etc.

  11. SMF reporting tools

  12. Rexx panel programs for TSO

  13. Panel/Rexx programs for TSO

  14. LOGREC cleaning JCL

  15. Creating users on TSO (Patata approach, which works very nicely)

  16. Sort jobs example with IBM Sort (Iceman)

  17. My .X3270pro file (UPDATE: NOW WITH TURBOPASCAL theme)

  18. My RSCS config file for HNET

  19. ISPF Panel Rexx examples

  20. JSON code for interaction between Golang and DB2

  21. My c3270pro file with keybindings for z/VM, VM/370, MVS and z/OS

  22. A z/VM machine load information utility

  23. A working copy of the original CHRIMAS EXEC (OR CHRISTMA EXEC) worm from 1988

  24. A payroll report source code in MVT Cobol with test data and the JES2 output listing

  25. VM/370 extensions

  26. The TELPAR operating system for EDA (Electronic Design Automation) and ATG (Automatic Test Generation) of Stanford University

  27. A disassembler

  28. Sample parameterhandling jobs,

  29. submit bash script for z/OS or MVS workflow in vim

  30. 3270 extended attribute codes

  31. a link to an archive with a fully installed MVS 3.8 TK4- Update 8 with ISPF, BREXX, NJE38 compiler bug fixes etc.

  32. some very cool VM/370 add-ons.

  33. a tape with VM/370 games.

  34. and more...much, much more

Enjoy!
