Hi John, OBJective-C is a superset of C that is based on the Smalltalk programming language. It is available, with varying support on the three platforms of current concern, as well as the iPad, iPhone, iPod Touch, Mac, Windows and Linux. I'll try to fish out a good tutorial later this afternoon. Regards, Alex, Alex Jurgnesen, VoiceOver Trainer, Visit us on the web at: http://www.vipbc.org/ On 2011-02-02, at 10:13 AM, John J.
