Chuck, >> I do know the author of the presentation and he runs z/VSE.
Come on - ;-) - I know him too. And I even know the father of that idea. Back to Pauls original question- (in the light of the fact that it is for a z/VSE system) >> My understanding is that this snipet of code allows the caller to add >> PSW Key E and F to there PSWKey list. To be percise: sets the bits for SPKA authorisation >> Does anyone use this technique ? Is the op-sys itself considered to be "anyone"? For CICS it is in use to allow CICS to switch from non-privileged key (90) to privileged key (80 in z/OS or any other in z/VSE). >> Does anyone have a routine like this that is coded differently ? There are certainly other ways to skin a cat- but to set a bit in a controlregister this method certainly fits Or are you asking for the ORG *-32 DC X'00000008' ORG I vaguely recall that this fixed a problem with IBM-code which is addressed/fixed meanwhile. Should I find out for you? -- Martin Pi_cap_CPU - all you ever need around MWLC/SCRT/CMT in z/VSE more at http://www.picapcpu.de
