I just wanted to add couple of additional points to Nelson's excellent

This is true. If you're using *new in a program that's called repeatedly,
you're going to feel the pain. :)  In those situations, I use a named AG
myself, but QILE would work if you don't have to worry about shared ODP's.
For more on the named .vs. QILE issue, refer to an earlier thread on this
same list:

With respect to trigger programs, they should run in *caller so that they're
within the commitment control boundaries of the calling application.

Or use CEETREC.
