Yes, I did forget it, cause I have used it only once; After reading that
wolfgang said it was faster then mul, i used the search replace in RosAsm
an changed all of them in one second. It turned out, only one of them
caused a bug. Such things you can do in HLA ? Its not monofile, has no
ide. ;-) You had to load up one crappy file after the other, oh lord what
a mess, poor sufferers. But you are a FASMite arnt you, so HLA doesnt
apply to you anymore ? :-))) Hehehe
