That was my thinking exactly
FIXED=USER on the DCBE fixed that problem but what about BSAM where
everything is 24 bits don’t remember this issue

And of course page-fixing a buffer cannot be an input requirement for any
service that supports unauthorized callers because those callers do not have
access to page-fix functionality (either by subpool choice or by the services
that do it).

Does BSAM (or EXCP for that matter) support above-the-bar real storage
for I/O operations? Format-2 IDAWs or MIDAWs and all that?

Seems like this is the only way my read worked but it kind of doesn’t make
sense
I should be able to have the I/O area from subpool 0 pageable storage
