I should not be playing with storage above the bar but I guess I'll use STMG to be sure.
Thanks everyone for their input! Much appreciated!

You are passed a 144-byte save area, so I would use STMG to save the registers in F4SA format as documented in Chapter 2 of the Assembler Services Guide. If you are sure that you won't be altering the high halves of registers 2 through 12, STM is adequate. -- Tom Marchant ---------------------------------------------------------------------- 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
