Subject: Is a page protected?--how to determine


Hello: I have a need to determine if an address in storage is page protected
in order to determine if a PGSER UNPROTECT needs to be done.

The best I have tried and seen in earlier posts is to look for a CC=1 on a
TPROT backed up with an ESTAE.

Are there any other methods to do this?

Thank you.

Paul Schuster
