I've done: IC R15,C' ' SLL R15,24 and LGFI R15,X'40000000' and LY R15,PADCHAR ... PADCHAR DC C' ',X'000000' What I'd like is to do something like the LGFI (or LLILH) but using the more "self documenting" PADCHAR format. I'm probably just too picky. I could probably write a SETPAD macro and use SLL, just haven't tried that yet. *Mark Hammack* [email protected]
