A mainframe die-hard I have written lots of programs over the years, some better that others I readily admit. Here is what I consider those of most general interest.
They include stuff I did not write myself, but are public domain and not otherwise easy to find, or that I think deserve a wider acceptance. So click here or on the Programs tab and see if there is something you can use. My programs do get updated from time to time, so please come back.

The CBTTAPE.ORG website is where you will find the most of z/OS and MVS freeware stuff. I have used a number of programs from there over the years. And contributed too.

An then of course there is the Links tab. Everyone else have one, so I do too.
