The syntax of PLO is of course PLO R1,D2(B2),R3,D4(B4). For many of the operation codes (5, e.g.) R1 and R3 (in the syntax, not GPRs 1 and 3) are unused. What is the recommended practice for what registers to specify? It seems odd to me that the PoOp is silent. GPR 0 would be the obvious choice, but it is specifically dis-recommended for R3 under certain circumstances. I kind of have a funny gut feeling about specifying a particular GPR other than 0.
What do people do generally? Or am I missing something in the documentation? Charles ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
