Thanks, Seymour, for the info about type-6s.
WRT GUPI, like most other ISVs, I use them when I can, and accept the
occasional recoding obligations when I can't.
My real question is... What happens when a type-1 SVC SUSPENDs? (Or
for that matter, when any other locked or disabled environment SUSPENDs?)
Thanks,
Dave

MVS used to store the registers in the TCB, but that's not GUPI, so
even if z/OS still does there's no guaranty that a later release
won't break it.
Type 6 runs disabled out of the SVCFLIH and can't hold locks.

Subject: Type 1 SVCs
I have an ancient question... It seems to me I should know this after
all these decades, but... I don't.
While a type-1 SVC is running, where is the resume state data
(registers, PSW, etc.) stashed?
Is it the same for type-6?
And while I'm at it, what are the differences between type-1 and
type-6 SVCs, anyway>
Thanks,
David Cole
