I think the reason is that Chuck is using the LOOP instruction to 
implement NEXT, which checks for ECX to be zero before conditionally 
branching.

Personally, I would check for sign after doing a DEC ECX instruction, 
which would get you your desired behavior.  But that's just me.  :)

ANSI is mostly consistent, fortunately.  Just don't use length-prefixed 
strings (unfortunately, WORD produces such a string as its result).
