Extended is the default for all non-ESDS VSAM files. I can't remember what it was, but we had some problem with ESDS files with Extended Addressing (perhaps in CICS). I may try to reduce the number of files in the FILTLIST. I was trying to duplicate the current compression environment, but that is likely overkill. Of course, if a file expands "for no reason", people will complain. And the DASD allocation report will show a sudden spike. Which will cause "weeping and wailing and gnashing of teeth" in management. -- John McKown Systems Engineer IV IT Administrative Services Group HealthMarkets(r) 9151 Boulevard 26 * N.
