James,

If you want to snoop around uninvited in a generic "other" address space
that may or may not be swappable, the only method I would recommend is
SRB.

IBM have made SRBs a lot easier with IEAMSCHD - well worth a look if you
are not familiar.

Subject: Cross Memory and AR ASC Mode

For a space-switching PC routine (PC-ss), I am aware of the requirement
for the service providers' address space to be non-swappable. However,
when in AR ASC mode and accessing data via an AR, is there any
requirement for the target address space to be non-swappable? I have
looked through the z/OS Extended Addressability Guide but I can't see
any (obvious) reference to this.
