Why not change the type of n to LONG rather than using a cast?

Hi Mike, Long answer (no pun intended): There were two ways to jump: I could either have, as you say, made n long, so it could accept negative values, or kept it unsigned and used a cast. I thought about K & R and character-reading functions taking intS, because of EOF. But I decided that that was because EOF was a 'legitimate' value; whereas, in this case, n was inherently a positive commodity and would go negative only in the case of an error condition. Short answer: OK, I'll resubmit using LONGs. Thanks for taking an interest. -- Andy.
