This article was previously published under Q26707 SUMMARY
You can use a cast override to change the operand size for the LOOP
instruction. For example, use "LOOP dword ptr alabel", so that in a 16-bit
segment, ECX will be used instead of CX. If you use a WORD override in
a 32-bit segment, CX will be used instead of ECX.
