Just a quick mention.... Rexx was created in 1974 by Mike, it was ANSI certified in 1996. As a former mainframe developer, I have had to use REXX and CLIST as far back as 1984 .

REXX is far, far more than an automation language. Despite the good intentions of this tutorial and the fact that it is a decent introduction, to imply that it is "mainly used for automation" is completely wrong, does a huge disservice to the viewers, and, perhaps, to the language. You can do many more things, more concisely in REXX than in any other programming language. REXX is easy learn and intuitive to use. It can be used instead of JCL, CLISTs and COBOL with one language and in the same modules. Under z/OS and z/VM, it productively interfaces with almost all facilities and does so in ways that are unproductive or impossible in other languages. I would suggest that you ask someone with more expertise to review your material for advice before publishing it. While I have been using and lecturing about REXX for more than 30 years I am still discovering things that I never expected to be able to do.

Hello Kumar

I wanted to thank you very much for this REXX tutorials- I have been trying to understand better REXX and CLIST and was wondering if, like CLIST, can I develop in REXX an user interface that allows for ad hoc JCL submission of load and extract series of jobs customized for different environment?
Again, thank you for sharing your knowledge

It wud have been better if u demonstrated the example in mainframe
