Willy Jensen

My name is Willy Jensen and this site is about my IBM z/OS public domain programs.

I am a retired but not necessarily idle z/OS system engineer. See
the Who am I page for details.

If you find something you like, just download and try it out. Most of the files are in the TSO XMIT format, though some are small and do not need any support files, they are in plain text format. Refer to
this page for how to handle XMI files. Start by reading the doc if available, it will be a text or a PDF document, or both. If you program using REXX you should at least look at the REXXGBLV program. The programs do get updated so check again from time to time.
Applied technology is knowing which wrench to use to pound in a screw.

There are 10 kinds of people in the World, those that understand binary and those that don't.

How to use XMIT files -
  • Download to your PC.
  • Upload to z/OS host to a dataset with recfm FB, lrecl 80 and blksize 3120 (larger value will work, but 3120 is guaranteed.
  • Do command TSO RECEIVE INDA(upload.dataset.name) repond with target dataset, it will be created if ts does not exist.
