appreciate all the feedback.

I'm aware actgrp's do much more...

I'm trying to put together some presentation material for a more jr.
audience and I think comparing actgrps to inlr could be helpful.

Also from my understanding INLR (rpg) is very much like STOP (in cobol)
right?
but yes, ACTGRP spans all ILE languages and has a universal behavior

thanks for all the things to consider

Jay,

Essentially, setting on LR in OPM destroys the current program
activation. Destroying an activation group, similarly, destroys a
program activation. So in that respect they are the same.

But:

Activation groups can be a GROUP of activated objects (programs and
service programs) rather than just one, so you can clean up "all your
junk" at once.

Activation groups can have memory allocations, commitment scopes, and
file overrides scoped to them.

Activation groups apply to all ILE languages (whereas LR only exists in
RPG.)

Activation groups support teraspace storage and (potentially)
multi-threaded access.


I could go on... so yes, there are some similarities, and that's a handy
way to think of things. But activation groups can do far, far more.

Instead of turning *INLR on or off to manage persistent memory storage
and
files opened, actGrp's pretty much do the same thing.

What are any real big differences between the two?

in a call stack...

OPM - pgm1 (inlr=on), pgm2 (inlr=off), pgm3 (inlr=off), pgm4 (inlr=on)
really isnt any different than...
ILE - pgm 1 actgrp(*new), pgm2 actgrp('named'), pgm3 ( 'named'), pgm4
actgrp(*new)

for the opm, on the next call, the pgms with inlr=off will still have
their
files/memory still resident, and the others will not
for the ile, on the next call, the pgms with actgrp('named') will still
have their files/memory still resident, and the others will not.

yes? no?

thanks

Jay
