You can start with the IBM manual, z/OS TSO/E REXX User's Guide. If you want a text book there is "The Rexx Language, A Practical Approach to Programming" by Mike Cowlishaw, who wrote the Rexx language. I would also join the TSO-REXX listserv so that you can ask questions to the group.

Even though it was nice to have a bit of BPAM practice in assembler I can see that this sort of thing would be far better written in REXX. One problem I have is that I don't know REXX, something I would rather like to remedy. Can anyone recommend a book on REXX in the z/OS environment ? Thanks, Bye for now, John.

So it is ease of coding vs. cost of running analysis. If this is run 100s of times a day, then I'd go with BPAM. If it is run once a month, who cares? But it seems silly, to me, to design HLASM code in a CPU inefficient way. If CPU doesn't matter, use REXX.
