I have formally retired from developing / teaching z/OS-related course materials.
- It's been a great run, but time to move on.
(Well, OK, if you want to discuss purchasing any of my materials privately send me
an email and I'll see what we can do.)
- (My training materials cover:
- Application programming for z/OS
- ISPF / Dialog Manager
- CLIST
- REXX
- JCL
- Assembly Language
- COBOL
- VSAM
- Language Environment (LE)
- Introduction to z/OS UNIX)
I'll continue to maintain this site for other purposes...
- Support my main email address
- Historic support of my role with Denver / Takayama sister city committee
- Use as platform for new endeavors as I choose
I also continue to support my other site
