My name is Willy Jensen. 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. 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.
