Thanks Conrad for that full explanation which I now fully understand. Actually the way I think of it now is that in this example "textField" is really the name of a *method*. As Ken stated earlier it's merely an error in the tutorial code. For which I'm very glad since It made me carefully re-read the Declared Properties chapter of OBJ-C 2.0. One key thing to remember is that @property occurs in the method declaration list. Another is that @synthesize generates accessor *methods*; So that in the expression if (sender == self.textField){senderName = @"textField"; } we are invoking the accessor method textField. As with any local method we need self. My first use of Obj-C 2.0. Yippee I learned something today.
