It only took TPF and its predecessors 35 years to get this right. :-) Way back in VM/370 R3 I had a diag that could be used. We did talk the ACP Systems folks at TWA into using the diag instead of touching Every page. We also had a mod in SVS to do the same (among other things). > If I remember right, it tries the first page of every > architectured segment. It could be worse. Earlier systems (OS/360, MVS line of systems, ACP, VM, etc.) touched every page. The touching was usually done by setting the storage key. Regards, Richard Schuh
