The compiler is perfectly correct       in rearranging the way the counter works.              What it did was rearrange the loop so i is decremented to zero,       which makes the end check *free*, because the dec instruction will       set the zero flag.              If you want transparent code, turn your optimizations off.              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
