MVS used to store the registers in the TCB, but that's not GUPI, so even if z/OS still does there's no guaranty that a later release won't break it.
Type 6 runs disabled out of the SVCFLIH and can't hold locks. ________________________________________ From: IBM Mainframe Discussion List <[email protected]> on behalf of David Cole <[email protected]> Sent: Friday, November 26, 2021 2:16 AM To: [email protected] Subject: Type 1 SVCs I have an ancient question... It seems to me I should know this after all these decades, but... I don't. While a type-1 SVC is running, where is the resume state data (registers, PSW, etc.) stashed? Is it the same for type-6? And while I'm at it, what are the differences between type-1 and type-6 SVCs, anyway> Thanks, David Cole [email protected] (personal) [email protected] (business) 540-456-6518 (cell) ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
