Are these mainframe developers or system level guys. I wouldn't use REXX to run production batch processes. I would use REXX for TSO utilities and ISREDIT macros. JCL is pretty much a must for running batch processing. It is waaaaay more simpler and re-startable than trying to do the same thing with REXX.
Hmm. I guess I am just not seeing the use case but not saying there isn't one. JCL, isn't hard to do. You usually just copy 80% of it from other jobs and change dataset names, etc...
