Yes, "keyed BDAM" was (and is) a supported (if little used these days) access method. AFAIR, "keyed BDAM" was one of the 3 file types supported by PL/1 F "REGIONAL" files.

Peter -----Original Message----- From: IBM Mainframe Discussion List <IBM-MAIN@LISTSERV.UA.EDU> On Behalf Of Steve Smith Sent: Thursday, May 12, 2022 3:14 PM To: IBM-MAIN@LISTSERV.UA.EDU Subject: Re: The Story of Mainframe Passwords 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 <t...@tombrennansoftware.com> wrote: > Yes...
