I'm not saying you shouldn't use relative instructions in macro's. I'm saying that you'll get value from modifying programs that have multiple base regs. If you don't regain any registers, then what value are you getting from relative instructions.
The relative branch instructions are faster: they don't suffer the Address Generation Interlock delay that their register-based counterparts do. So, yes, any program should benefit from converting. That said, the "COPY IEABRC" technique is probably best for modifying older programs. ---- Bob Woodside Woodsway Consulting
