Using TRUE EQU YES makes your intent clear. Coding X'FF' would be consistent. -1 should not be used. > I realize that bytes are unsigned whereas anything bigger is signed. Numbers in HLAsm are signed or unsigned and have a length of 2, 4 or 8 bytes (ignoring float & packed). 1 byte is not considered a number. > it would be nice if the assembler "understood" that x'FF' and -1 are > "equivalent" In C, they are equivalent but HLAsm is warning us that it's making an assumption about our intent. > MVHI (and MVHHI for a halfword bool) doesn't sign extend I'm not familiar with these instructions but I assume they are for the C compiler. If there aren't signed equivalents, then I'm guessing the C compiler did not need them.
