I have a similiar situation except it is all dynamic calls.  A CL (not ILE)
calls an RPG IV program which calls several different RPG IV programs, all
of it dynamic calls.

I compiled the first RPG IV program as DFTACTGRP(*NO) ACTGRP(*NEW).  The
other programs are all DFTACTGRP(*NO) ACTGRP(*CALLER).  When the first RPG
IV program is called by the CL, a new activation group is created.  Since
the rest of the RPG IV programs are *CALLER, they all run in that same
activation group.  Since I use *NEW rather than a named activation group,
when the first program ends, the operating system automatically reclaims the
activation group, so RCLACTGRP is not needed.

Unless you are getting really sophisticated with activation groups, I see no
purpose for named activation groups, QILE or otherwise.  If you want
programs to run in a separate activation group and that group to be
reclaimed when the programs end, use *NEW for the outermost program and
*CALLER for everything else.
