I agree with the Scotts (sorry, couldn't resist!) that service programs
should be *CALLER but you can indeed activate a service program from OPM and
in the default activation group under these circumstances:
OPM pgm
call ile ag(*caller)
callp proc in *srvpgm ag(*caller)
Under this arrangement, the ILE program mainline and the service program all
run in the default activation group. Now you can't destroy this activation
group, so there won't be any issues regarding program activation after
destroying the AG, so you'll probably be OK even then.
If you intend to follow this pattern, may I humbly suggest that you
carefully read through the ILE Concepts guide to see the differences between
an ILE program compiled as DFTACTGRP(*YES) and one running in the DAG
because of *CALLER.
