Are you sure switch makes the same kind of code as above ? I thougth it 
made a lot of compare/next steps !

Guess I need to look more into the generated asm output (not been doing 
this for a while) !

That would be wery strange code indeed, and I will be happy if switch 
make the indirect goto jump for me, as this will be quite speedy ! Next 
step will be a compiler :-)
