Each time you see that you have done a mistake you go to assembly man,
that's just to impress people here.

Well, you are not going to do that here in general, nor with me in 
particular. I know enough assembly to know when to use it. That
routine doesn't do anything where an assembly language program would
be much better.

Places where assembly shines are computations and operations that have
NO equivalent in higher level languages. That is surely not the case
with the small routine above
