But we do. We use "or" to mean "xor" in English. e.g.: "You may have the Ice-Cream _or_ the Candy-Floss." This quite obviously means "one _or_ the other, but not both". Which is the definition for "xor"... :) What we don't have is an equivalent for the logical "or"! -- Carl R White -- Final Year Computer Science at the University of Bradford E-mail...: cyrek- at -bigfoot.com -- Remove the hyphens before mailing.
