Thanks Peter for taking the time to make the clarification. -----Original Message----- From: IBM Mainframe Discussion List [mailto:IBM-MAIN@LISTSERV.UA.EDU] On Behalf Of Peter Relson Sent: Tuesday, September 11, 2018 7:52 AM To: IBM-MAIN@LISTSERV.UA.EDU Subject: Re: Spectre/Meltdown APAR - OA54807
**CAUTION EXTERNAL EMAIL** **DO NOT open attachments or click on links from unknown senders or unexpected emails** No code outside of z/OS itself should ever be referencing PSASTAK. That is why it is not a programming interface. It has moved before. If you are referencing it, you either wrote that code after the previous move, or you accommodated the previous move, or you have been broken since the previous move (those are the only choices I could come up with). If you have to reference the normal FRR stack for some , use the pointer in PSANSTK. That is why that pointer exists (although it too is not a programming interface). Regardless of the OSPROTECT setting, the PSASTAK change will be in effect once you are running with OA54807.
