When I first started writing triggers, I assumed that the only way to get
good performance was to leave LR off when I exited the program. All
subsequent calls in that job would then use a program that was
already loaded and initialized. I now understand that programs (PAG
portion anyway) do not get cleaned up automatically when a program
ends even with LR on. All subsequent calls to that program are faster
because of the lack of cleanup for a named Activation Group.

As a rule, I use DFTACTGRP(*NO) and ACTGRP(QILE). Should I
still leave LR off when I exit my program and code it to be re-enterable?
Or can I seton LR and let the system handle re-initialization without
any real penalty?
