I should know better than to debate this with you, Jürgen, but it's too tempting! It's because, to me, Pascal is an extension of mathematics and logic; and in the languages of math and logic, such constructs make perfect sense. The fact that I cannot use 'in' on certain types of things in Pascal makes it less elegant than mathematical language. But anyway... my guess is that it's not happening anytime soon ~David. _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
