Reasons to use a *PGM:
===================

1. it is to be invoked from a command-line, e.g. via a COMMAND
interface, or from a menu.
2. it will be submitted to run as a batch job, to:
* generate a report
* perform an end-of-day consolidation process (like in banking)
* perform some kind of "merge/purge" processing
* etc.
3. it will be called from some "client/server" interface that expects
to CALL a *PGM

​Note that it's quite easy to create a *PGM wrapper around a procedure in a
service program​. ILE CL works well quick nicely (as does ILE RPG of
course)
pgm
callprc myprocedure)
endpgm


So don't think that just because you need (or may want) to submit a process
to batch stop you from putting the logic into a procedure.

The converse is not true, you can't really put a procedure wrapper on a
*PGM.
