Well that sounds like what I'm looking for. All I want to do is to be able to transfer the script onto another computer (which doesn't have Ruby installed) and run the script. From what I've seen by playing with it on my computer, it doesn't seem to be as simple as just copying the ".rb" file. But thanks a lot for the comment, I'll have to check out that book you mentioned. -- Posted via http://www.ruby-forum.com/.
