Which assembler are you using? I'm just mildly curious because as best I can 
remember asm was case-insensitive and RMA was case-sensitive. It's been a 
long time since I poked into the guts of these beasts, though. If I need to 
assemble anything these days, I usually use mamou from Toolshed and copy the 
binary to a VHD.
