RE: A different kind of persistence?

Eric,

Wow.  That's interesting...and just a little disconcerting.  What
purpose does this serve?  If I set on LR for the calling program, I
would have certainly expected all bound modules to end at the same time.
Man, I need to go back to the books on basic ILE I think.

Let me ask one more thing.  Will a service program behave the same way?
Once it is used in the AG, will it persist?

Thanks,
Dane

Dane,

Your q:
"Eric D. - yes, I think all of what you stated is accurate.  Named
activation group for all programs (*PGM objects) called from this job.
However, some of your comments contradict those of Bob C's regarding the
persistence of data.  Does LR have no impact on global variables within
an activation group...period, the end?"

LR has impact within the scope of the module where it was set.  In this
case, you set LR in the MAIN module of your program, and not in the
NOMAIN
module.  For the storage defined in the NOMAIN module to be
re-initialized,
you would need to seton LR before returning from that module.  This sets
a
switch that causes global storage to be re-initialized on the next call.
(Note that this has no effect on local static variables that are
declared in
the procedures.)

Even though you are binding the module by copying it into your *PGM, the
rules of activation group resource scoping are still at play.  Once the
module get started in the AG, it remains persistent until the job ends
or
the AG is reclaimed.  Setting LR within the module does not cause
resources
to be reclaimed as they do in RPG/400.
