People say "that is batch" or "that is online." I think online means CICS screens and batch means JCL jobs overnight. Is that close enough?

Close enough for week one.
Batch = job runs without a user sitting there, usually scheduled, reads/writes files or DB2, ends.
Online = interactive transaction, someone hits Enter, CICS runs a program, sends a map back.
Same COBOL skills show up in both. The runtime wrapper differs.
