RE: H ActGrp('QILE') vs H ActGrp(*caller)

This is good, it made me look up activation group deletion.  TFM (RPG
Reference) says:
*******************
When an activation group is deleted, its resources are reclaimed. The
resources include static storage and open files. A *NEW activation group is
deleted when the program it is associated with returns to its caller.

Named activation groups (such as QILE) are persistent activation groups in
that they are not deleted unless explicitly deleted or unless the job ends.
The storage associated with programs running in named activation groups is
not released until these activation groups are deleted.
**************************
There's more of a difference between *NEW and a reg named activation group
than I thought.  For batch jobs the difference can be smaller than for
interactive jobs.  It's terrifying how much more you can learn if you
actually read the book. <g>

BTW, I don't know what I was thinking about multiple instances of the same
(user named) activation group.  Even I know that's wrong.
