CBT Software for MVS 3.8

There is some really useful software contained on the CBT tape, but sometimes it requires a bit of manipulation to get it in a form that is usable on MVS 3.8 as most of the mainframe computing world is currently using some flavor of OS/390 while we are back in the past about thirty years on an operating system most people would refer to as obsolete.  Some of the software that I get working and find that I use frequently I am going to include here on this page.

On the page for the each module listed below I will include:

  1. a description of the software

  2. where it is on the CBT tape

  3. sample output (if any)

  4. the jobstream I used to install to software, which will include the modifications required to the software to install and/or run on MVS 3.8

You can always retrieve the software directly from the CBT site (https://www.cbttape.org), but for at least some of the programs you will have to make modifications similar to the ones I have made.

November 2014 Update

At various times I have retrieved items from older versions of the CBT tapes.  The older versions are available from the CBT.org site, but are mostly available as tape images, which require some work to reload before individual files may be accessed.  I have begun to revisit some of these versions and in the process am organizing them in such a way to be able to stow them on my site as individual volumes.  Therefore, if anyone needs to quickly access an older version of the CBT 'tape', they may download the image, attach it to their Hercules' MVS system and have quicker access.  To access these older versions, follow this link: Older CBT Versions
