If I do the RESTORE the current way and back off 10
SYSMODS only to do the APPLY and apply 9 of them, why is
this "safer"/"more correct" than just doing a forward
APPLY of those element(s) of the backed-off SYSMOD that
were taken from the other 9 SYSMODs during the Apply step
that was done after the Restore?
I've cursed SMP for the same reasons. However, I can
think of reasons that the current method is safer or more
correct:
1. If you've Received Holddata between the Apply and
Restore, it may be that one of those other Sysmods is PEd,
SUPed, or some such.
2. If any of the 10 had JCLIN, things could get
tricky. Especially tricky if the one you're Restoring had JCLIN.
3. SMP won't know if you did any BYPASSes when
Applying. If you had, things could get tricky. Better
that a person do trickiness than trusting it to SMP.
Also, IBM has limited resources for SMP
enhancements. I suspect it would be easier to code SMP to
Restore all 10, then automatically re-Apply the other
9. (Or, at least, automatically create the control cards
for doing so.)
