Talking with mainframe guys for the last half decade, they seem to avoid JCL when they can and treat REXX like a super power.
- cwbriscoe 3y agoAre 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.
- YeGoblynQueenne 3y agoYes, but you use the REXX to generate the JCL.
- cwbriscoe 3y agoHmm. 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...
- YeGoblynQueenne 3y agoYes, automatically :)
