Depend on rather or not the program is still active in a given job...
If DFTACTGRP(*YES), then did you return with *LR = *ON?

Otherwise, will depend on rather or not the activation group is still
active.

Best practice for triggers to to leave them active...

What I am trying to do is this: The program is reading 4 data areas using
'IN' statement. I have found that the IN statement is about 7-8 times more
'expensive' than CHAIN. I am trying to figure out if there is a way to
increase the efficiency of the Trigger program. All the 4 data areas are
really static, but CAN be changed, hence the 'IN' statement for every
cycle.

That seems hard to believe...I'd suggest making sure you aren't trying to
lock the data area unless you intend to update it.

But in any case, simply use a global variable as a flag to indicate you've
already read in the data area...possibly with a timestamp so you could read
it every so often in case it's changed.
