Agreed, silly is bad.

"automatically cleaned up" comes at a price.  If the program is called
again, the program will incur
the overhead of creating another activation group.   This is the difference.
No free lunch.

Buck's example (*NEW only at the menu/top level) is a good usage.  No
unnecessary AG creation or a *CALLER pgm that's called from the default
activation group.    Of course either would be silly, but like bugs, it can
happen.

Those who aren't sure about which pgm to make *NEW/*CALLER would probably do
fine with the non-default activation group "default" (QILE).
