Re: Call stack inquiry performance - QWVRCSTK vs QMHSNDPM+QMHRCVPM

["Carel Teijgeler" <coteijgeler@xxxxxxxxx>]

Should that PGM not be in the call stack, if other (SRV)PGMs pass the name
of that PGM on?

Or:
Why and how would a PGM pass on a PGM name, when it is not in the call
stack?

Or:
You want to check if the PGM is already in the call stack, because the
SRVPGM can call it, if it does not? (Activation Group *NEW, perhaps?)

I do not understand this implementation of this.

To answer your question: ir depends on the size of the call stack. Many
PGMs open, I would use the PGMMSG approach.

With regards,
