If you're concerned with trace-backs for debugging, you might want to stick with standard save area formats. They are documented in Assembler Services.

That is why I'm sticking with the original 72-byte save area and just adding 16 words to the end so that I can save the high halves of all 16 general purpose registers. A hermaphrodite situation but you do what you can with what you've got. Thanks.
