Maybe confusing with some utility from Mr Mark Zelden

I don't recall SHOWMVS being written in REXX, although there is definitely REXX code on the CBT tape. -- Shmuel (Seymour J.)

External Message: Use Caution I have a z/OS programming task that I wanted to get some clues on how to accomplish, and I went to look at SHOWMVS for ideas. My copy seems to have gotten away, in one mainframe upgrade or client change or another. I downloaded SHOWZOS from the CBT site and it seems to be written in assembler. I recall SHOWMVS being written in Rexx. Is my memory flawed? I can certainly read assembler, but (IMHO at least) it's a lot easier to answer "how do you do that?" from Rexx as opposed to assembler. Is the source for SHOWMVS still available anywhere? (Not from FILE183 on CBT.) Am I thinking of some other program? Is there something "like SHOWMVS" that is written in Rexx? Sorry. This feels like a dumb question to me, but I am searching my brain for an answer.
