May I ask why you need to switch to key 9? That is very atypical. I
believe that the Storage Protect Override facility, as implemented in z/OS
with Key 9, was created so that CICS transactions could avoid accidental
overlays of CICS key 8 storage. So unless you're trying super-hard to
prevent yourself from overlaying your own key 8 storage, you would not
typically get into key 9.

Hi Peter!
I'm playing around with some tests and was switching keys,
and didn't want to mess with authorized code. So I just picked
the next one up to 8. There was nothing "special" in my choice
of 9.
Same kind of idea - trying to just switch to key 9 and make sure
things don't blow up, or accidently reference the previously allocated
key 8 memory.
But I bumped into some references to the previous memory that
are intentional/needed... so it's a bit of a squirrely mess at this point.
