Martha,
My recollection is that there's only an allocation bit map on a
page-extent basis. The only way I can think of to track down the page is to
figure out what the CCPV value* is for the page, then traverse all the
PGMBKs for the suspect users, looking for a matching DASD slot "address" in
an ASATE. It's distinctly brute force and requires a lot of control block
chasing, but another approach does not immediately come to mind.
* CCPV= 2 bytes of cylinder number within the page extent, one byte of page
number within the cylinder, and one byte of index into the CPOWN list
(V=volume).
Marty
