CBT Tape: Updates in the last 6 months

By | June 18, 2024

CBT Tape s an open library of free software distribution for the IBM mainframe Multiple Virtual Storage (MVS) and OS/390 and z/OS operating system environments that continues to evolve to meet today’s modern needs. The collection of free software is generally updated “version-wise” about twice a year.  This does not mean that you can’t get to updates that came in-between times.  Those updates can be found on our website. As a part of the Open Mainframe Community, CBT Tape benefits from a broader ecosystem that will raise awareness for this extensive library and introduce it to a new generation.

WHAT CONSTITUTES A “CBT TAPE FILE”?

Most CBT Tape files consist of a PDS, or partitioned dataset, which you can picture as a subdirectory.  A partitioned dataset contains one, or many “members”, each of which is a data file or a program.  In order to load a partitioned dataset onto a single tape file, it has to be “sequentialized”, or in other words it has to be converted into a single individual file, before it is copied to tape.  This process is done by the use of several programs that come with the collection, and which are used for this purpose.

Some single CBT Tape files contain several hundred programs.  With more than 1000 files in the CBT main collection, and more than 300 files in the CBT Overflow collection, the entire collection contains thousands of tools for systems programmers to use.
