Some of the new formats are used in conjunction with a 72-byte save area, and you can definitely use them in A31. I don't know what LE supports (OCO delenda est!).

And they're not supported by Language Environment. -----Original Message----- From: IBM Mainframe Assembler List <ASSEMBLER-LIST@LISTSERV.UGA.EDU> On Behalf Of Steve Smith Sent: Thursday, January 20, 2022 9:52 AM To: ASSEMBLER-LIST@LISTSERV.UGA.EDU Subject: Re: Saving Caller's 64-bit Registers I don't know what you found, but that's incorrect. A standard Format-4 save area is 144 bytes, and there are additional formats (5-8) that can hold combinations of ARs and high-halves. As previously mentioned, the Assembler Services Guide defines all this. sas
