CA7 vs ESP differences

[tompatino]

I have used both CA7/CA11 and ESP in different installations. But, I haven't used CA7 in 6-7 years.
I know one difference is that in CA7, each job is scheduled separately, whereas in ESP, events are scheduled and each event can contain many jobs.
I would like other's thoughts on the differences and similarities between CA7 and ESP.

Also, I have used REXX imbedded in EPS procs. Can CA7 utilize REXX as well?

ultimately CA7 do not execute any thing.. it schedules the batch to some operating system. if the operating supports rexx, CA7 can schedule them.
I am using rexx codes scheduled from CA7 to run in z-OS

Thanks
