Echoing Binyamin’s post, why is this not simply flagged by the assembler? Assuming it’s valid code, Is the result of its execution to put the section offset of MYLABEL in the low half of R3 (leaving the high half unaltered)? Keven > On Nov 24, 2020, at 00:06, Binyamin Dissen wrote: > > On

Yes, definitely interesting stuff. I'm pretty pedestrian and have only used the newer insert instructions with actual immediate values, probably as the designers intended... IILF R2,C'HOLA' IILF R2,EquHOLA EquHOLA EQU C'HOLA' Resulting in x'C8D6D3C1' in R2. But when C'HOLA' is defined as

IILF and LGFI will load whatever is in the immediate operand. PoOps is perfectly clear on that. What goes into the high bit is an assembler issue, but anything but 0 would cause problems. If you're going to us it in, e.g., BASSM, the use FOO+X'8000' rather than FOO for switching to 31 bit mo

I thought I could segregate the SRB code which had references to external module Meaning put the external =V CSRC calls And keep it in the same Class from the doc it seemed that XATTR would have external module in the same class I could then move the entire class to CSA You seem to say
