If you want a collection with >multiple copies of values but no order, it's called a "bag", in >generally-accepted computer-science-speak. (As opposed to a "set", >which is a "bag" where every value appears at most once.) Sort of. A "bag" is different in that it isn't linear. Its basicly a set w/o the uniqueness requirement. I'm not saying that doubly-linked lists don't have any order at all. I'm saying that they have exacly *two* of them, and they are both equally valid. --- T.E.D. homepage - http://www.telepath.com/dennison/Ted/TED.html No trees were killed in the sending of this message.
