Hi there! I hope you don't mind me writing to you about an ada question. I got your name off the net. I am currently new to the language, of my own doing, after ada being recommended by a friend to improve my programming skills at work. I am now currently trying to implement relations. Like say domain and range, domain restriction and range restriction through an array based implementation. Would you know of how i could get some example code to look at please? Thanking you in advance, Darren. _________________________________________________________ DO YOU YAHOO!? Get your free @yahoo.com address at http://mail.yahoo.com
