Thank you Ian, and Sean. I'm surprised that I got a reply so quickly! I was just reading p404 of the Pickaxe book(1.8) and reading about ObjectSpace, but it was really brief, and I was reading it over and over until I started to begin talking to myself (not good). What I really wanted was to get the actual identifier of the object, but for now I'll create a instance variable for the actual identifier so I can put it in the to_s method, and I can get things working. I know it's not the Rubyist way, but I just started, so hopefully I can find a better way later and post it here. Once again, thank you guys. You were very supportive, and I would have not figured this out so painlessly without your help. Aki -- Posted via http://www.ruby-forum.com/.
