Our application software has no RCLACTGRPs.  I don't think it has any
RCLRSCs either.  It certainly doesn't where any service programs are in use.

As far as releasing resources, I write all of my service programs with a
procedure to close the resources, and most have a procedure to open them as
well.  At least one, maybe two, open resources only as needed because of
the nature of the services they provide.

I have an advantage over a lot of people in that there was no use of ILE
functions where I work before I started it.  All RPG IV programs used to be
compiled with DFTACTGRP(*YES).  I write and maintain all of our service
programs so I make sure that they adhere to the ILE standards that I
developed, said standards including:
1. all service programs are *CALLER.
2. no named activation groups for service programs or regular programs.
(Someone could compile a regular program into a named activation group, but
since I provide a set of standard H-spec /COPY members with activation
group keywords, it's very unlikely.)
