Started in data processing, that's what information technology was called then, back in 1972 as a JCL Clerk. Moved to junior sysprog within 2 years and then senior sysprog after 2 more years. Started with MVT 21.7 and now work with z/OS 3.1.
Over the years my focus has been on making the environment I work in as productive as possible resulting in developing tools, and documentation, that I have been allowed to share with the mainframe open source community. I have also been active at SHARE in various capacities.
I am now a software developer for Trident Services and still have management support to participate in mainframe open source.
Many of my open source contributions can be found at https://cbttape.org and on m GitHub site at https://github.com/lbdyck.
