VSAM does not use hardware keys. What I know of that does are PDS directories (KL=8) (not PDSE), VTOCs (KL=44), SYS1.BRODCAST (KL=1), and just heard about PASSWORD. They are (of course) available for user application with BDAM (Google suggests I meant "BDSM"... almost appropriate ;-). I don't know whether ISAM ever used them.
They're basically a relic from when DASD was much much slower, and much more expensive. sas On Thu, May 12, 2022 at 3:04 PM Tom Brennan <[email protected]> wrote: > Yes...
