Yes, I quite right! I merely wanted to point out, that one shouldn't
make statemens like " *s++ = *p++ is ALWAYS better than s[i] = p[i]; ++i"
and gave ONE counter example (Intel machine + large memory model).
I think it's very good practice occasionally check the assembler code
your high level language compiler procudes. I do generally this kind
of thing after a program works. And sometimes I change my coding as a
result (if I feel the relevant spot of code is critical).
