Sure, that would be great. :) I would understand the comments a lot better than the code. :) Maybe I could figure out a QBasic port by reading your comments. :) _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp. _______________________________________________ Chat mailing list Chat at freenetproject.org http://lists.freenetproject.org/mailman/listinfo/chat
