This is not quite what I meant. MM_USE_DEFAULT will cause prompt to take the default action, which is fine if that is what the user wants. I am suggesting using PERL_DATE_CALC_NOXS as a way to *change* the default without having to answer the question. IMHO prompt() is nearly always a mistake. (Asking question by other means is *more* of a mistake, of course :).) Ben
