I recently used a CSA subpool in a user key and I got yelled at
From respondents to my problem
On the forum
The reason I did it was Front ended
ATTACH svc 42
And I remember that the JES initiator
Does an ATTACH to the problem
Program the address of the entry point
Name is a The initator subpool which is CSA but has to be KEY 8

Agreed... You are correct... she could allocate in another key.

As long as not in fetch-protected storage - what is to stop Key8/9
program from reading Key2/Key4 common storage ?
My product actually depends on this as all my "client" code runs
Key8 and all of the "server" anchors are in Key4.

Ladies and Gents,
She needs read access to this storage from unauthorized key 8/9
programs... the storage must be allocated in key 0.

I believe that IBM used to use Key2 for some purpose years ago, but
this is no longer the case.
Key4 has never been assigned an offical IBM usage.
There is no "hands off" for Key2 or Key4 as far as I am aware and
they are both frequently used by ISVs to avoid Key0 for the reasons
stated earlier.
There is nothing to stop in-house code from using these keys either.

Key2 and key4 are flagged in the Diag guide as "reserved". I presume
they are flagged as "reserved" for some vendor(IBM or OTHER) reason.
Can anyone enlighten me?

A frequant usage for this sort of thing is either Key2 or Key4.
If you store information in the Key2/Key4 block using MVCDK with the
correct key in R1, then you can reduce the likelyhood of storage
overlays even if your pgm is running Sup+Key0.
