How Do ya convert 2 WORDS to a DWORD????? :evil:
mov ax, bx
shl eax, 16
mov ax, cxIf size is of importance you could also do (using the same registers as the above post):
push bx
push cx
pop eax
what size advantage does your methode give? you mean of the compiled code?
Yeah, compiled code.

If you're concerned about size (which I imagine the OP probably isn't), then you save four bytes. It's certainly a hack (the code you provided is the correct way to do it), but may be useful to consider.
00000000 6653 push bx
00000002 6651 push cx
00000004 58 pop eax
