Re: Named activation groups vs *CALLER (was: H ActGrp('QILE') vs H ActGrp(*caller))

Jade,

The confusing thing about OVRSCOPE(*ACTGRPDFN) is that it means different
things in different situations:
- In the default activation group (OPM environment) it acts as it used to
act before ILE, or *CALLLVL.  That means it will be in effect until the
issueing call level ends (or the override is explicitly deleted).
- In any other activation group the override scopes to the activation group;
it will be in effect until the activation group is deleted (or the override
is explicitly deleted).
