Gee, I don't want to pose as an expert in the relative benefits of various Rexx environments. I have near-zero experience on 'nix and USS, no recent (15 years) experience on CMS, and although I have written large systems in Rexx, I am not at present writing much Rexx beyond basic "TSO helper" scripts.
I certainly don't want to contribute to an OS war. I was just answering the question about how to learn Rexx, and if you happen to have access to both, IMHO CMS is a more Rexx-friendly place than TSO. It's really a separate topic, but I think there is little doubt that it makes sense to edit code of any sort in some fast character-at-a-time interactive environment even if the target compile and/or execution environment is z/OS. My particular choice is MS Visual Studio, but I only claim that it makes sense for me, not that it is the best for everyone.

Before USS was available I tended to edit JCL on CMS with XEDIT; nowadays on Solaris, often accessing legacy data sets with NFS. NFS will deal with PDSE; I suspect that CMS would have trouble ACCESSing a PDSE, and writing to any legacy z/OS data set from CMS is questionable, as is catalog search. I use TSO/ISPF, now as earlier, largely for: o SDSF o DSLIST o DDLIST o Testing with a customer-like environment. I keep one ISPF session active, and as many USS or Solaris as convenient; I've never mastered WSA. (and I have one EXEC that uses ISPF LMGET to process RECFM=U (by override) data sets because EXECIO refuses to deal with U. That's reported to get better in 2.1.) Rexx SYSCALL is a boon (or a least it spares me learning Perl). ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
