Hi Mark, great site and tools. Thanks for all your value-add software and comments over the years. I'm retiring at the end of the month - but I'll keep editing JCL in my spare time. Cheers, Greg Nov 2025.

Thanks for allowing me access to the website.

Mark, I have used your site for many years, I appreciate everything you do. Your code has served me well over the years and it is greatly appreciated! However, I don't see any code for a retirement calculator, I can use one! Thank you again, this site is invaluable! Brian

Visited this page after 20 years. Mark's code is as useful as ever. This visit was fruitful, it helped me to pull few variables from cvt using the code in IPLINFO for the ansible coding effort. Thank You! Mark!

Mark, what is the Hex CVTOSLV6 code used on z/OS 2.3? I can see the RUCSA value today but have to use 'D IPLINFO,RUCSA'. I wound rather use your IPLINFO REXX program. Thanks

Thanks a lot, those Rexx are lifesavers
