Ben Schroeder>></blockquote><div><br>Thanks Ben, that makes a lot of sense. It's similar to how 1 @ 2 will return a point. And, of course, after reading your answer I realised that what I should have done is used the method finder to look up ->. I just haven't quite got it into my head that there are only objects and messages, and therefore if something isn't an object, it has to be a message! :-)<br>
