MVS Utilities

this repository includes some very useful utilities for people working with MVS, z/OS on real mainframes or emulated ones. 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 somall enhancement to the program. compile simply with gcc -o recv90 recv390.c.
  2. SYCPLK.ccdk is a 3390-3 volume (SYSCPK) which incluedes 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 many other goodies.
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. my PL/I implementation of the N x N queens problem
  5. Sorichetti's vpwpc output seprator for Hercules printers
  6. The usefuljcl/ directory contains very useful JCL jobs which you will use on adaily basis as a MVS or z/OS SYSPROG
  7. 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
  8. the PC370 source code for the simply amazing S370 assembler which runs in MS-DOS.
  9. Lots of JCL and source code files which I use in my moshix mainframe channel vidoes
  10. Some JCL for Cobol and VSAM on z/OS
  11. 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.
  12. SMF reporting tools
  13. Rexx panel programs for TSO
  14. Panel/Rexx programs for TSO
  15. LOGREC cleaning JCL
  16. Creating users on TSO (Patata approach, which works very nicely)
Enjoy!

Get a JES3 Complex Up and Running

UPDATE: January 19, 2019 The procedures here work for me and hundreds of others repeatedly and I have made a video about all this which you can find on Youtube here : Prerequisites 1. Hercules 3.12/Spinhawk/4.00(hyperion) with Peter Jansen's CTC extensions I use the Hercules as provied by the latest version of Juergen Winkelmann's amazing MVS 3.8J TK4- distribution (update 8) which you can get from here.  Notice that we don't actually use the MVS3.8J distrubution at all, we only use the Hercules binaries that come with TK4-. You find them under ../hercules/linux/64/bin 2. The MVS 3.8J with JES3 distribution from Kevin's website. Notice that I have a MVS3.8A and a MVS3.8B directory. A is for the global MVS image and B is for the local MVS image. You need both TK4A:   http://www.j76.org/misc/tk4-_ update_07.jes3_2016-09-15.zip TK4B:   http://www.j76.org/misc /tk4-_update_07.jes3b_2016-10- 04.zip Or you can also get them from here :  3. any 3270 t

IBM MVT 21.8F Distributions for Hercules

What's MVT? MVT is a beautiful operating system. Extremely reliable and a great way to learn and understand the modern day successor (or grand-grand-grandchild), z/OS.  When IBM announced the System/360 mainframe line in April 1964, the plan was to provide just one operating system for batch-oriented use, known simply as the System/360 Operating System (less formally as OS/360, or OS). OS was big, complex and ambitious for its day, and the resulting system was late, buggy and resource-intensive. Installations that couldn't wait, or couldn't afford the hardware required to run OS, opted for one of the smaller, simpler systems that IBM created as alternatives: BOS/360, TOS/360, DOS/360. Eventually, with most of the bugs shaken out OS/360 became IBM's flagship System/360 operating system. By the time of the final OS/360 release in 1974, system programmers building an OS system had the choice of two control programs: MFT, Multiprogramming with a Fixed number of

Old, old software

Lately, a bunch of 3420 tape reels were found. After converting them into electronic format, we unearthed several software products that were thought to be lost forever: 1. EDGAR 2. 5740-CB1 RELEASE 2.4 IBM OS/VS COBOL JULY 1, 1982 for MVS This is the follow-on release to the MVT Cobol that we know from MVS 3.8 TK4-. Both are ANSI Cobol compilers, but this one has a several novelties compared to the Release 1.3 of TK4-: an optmizer, VSAM support, a LIST parameter to create an assembler listing, and better RENT checking. 3.
