Yes, there is indeed a small window, which is a PITA. I have a batch job with 
commands which execute pre-prepared members and commands to shorten the time of 
the whole re-loading thing. Timespan - just a few seconds which is already 
undesirable for us too.

John, with that new REPLACE operand, I have 2 questions even after RTFM:

1. Is it still needed to reload SMFPRMxx after doing the SET PROG=xx?

2. Is it still needed in PROGxx to use EXIT DELETE and LPA DELETE and then 
later again with LPA ADD and EXIT ADD? If not, can I then just replace all 
those EXIT commands with one which is using REPLACE? 

TIA!
