Your higher language will eventually produce c code??? Then the c code could have either form being discussed but you will have no control over which. You have merely hidden the problem from your own view! If you create a "compiler" which converts your higher language to c, then you will still have to tell the "compiler" what form to use. What have you gained? : ) Bob D.
