This is where I have had problems trying to use *CALLER on my service
programs.  When called by an OPM, I sometimes get unpredictible results.  As
much as we all would like to see one simple solution to be used throughout
our shop, nothing seems to fit every situation. For this reason, I have
wound up with:

- *NEW for known, definite driver ILE programs.  Usually, menus and CL's.
(with the caveat that they aren't called repeatedly)
- *CALLER for programs definitely known to be called ONLY by those driver
programs.
- A specific NAME for small, tightly integrated, standalone systems.
- The name "TRIGGERS" for trigger programs.
- The name "SRVPGMS" for service programs (generic service programs, that
is, not those tightly integrated in to a standalone - system).
- The name "QILE" as a catch-all for everything else, especially where I'm
not sure at design time who will be calling the program.

This system has been in use for about four years and seems to provide nice
boundaries between sections of a job.  It's also quite helpful when looking
at the program stack.
