I think that your response has given me valuable insight into the code I attached earlier in that I now understand that the keywork 'self' refers to the object that we are currently in. But what is actually passed, a copy, or a reference to an instance of Example81? When we look at @app in the Car class what are .width and .height etc.. Sureley they would be methods of Example81 that have been inherited from the App superclass. Is this a fair assumption to make? JD -- Posted via http://www.ruby-forum.com/.
