LOOPWNE label       16-Bit 80386 LOOPWNE (TASM Only) Flags: O D I T S Z A P C

     Normally, whether or not ECX is used as the loop index is determined by
     whether the instruction is in a 16- or 32-bit segment. However, TASM lets
     you indicate that you want to use the CX (not ECX) register for LOOPNE
     regardless of the current segment with the LOOPWNE instruction.

     See LOOPNE for more information.
