I thought the CM KSAM "KSAM Control" information (statistical counts of access operations etc.) was kept in a user label on the *data* file. If this is true, then it sounds as though user label changes are *not* causing the modification date to be updated, which sounds like a fairly serious bug to me. Or is the KSAM Control stuff kept in the key file? G.
