OK, so can we get a real example of how to replace the *old* way with the new? In a case where there are several entry objects:
Form.Name Form.Address Form.Note I want to enforce a proper uppercase/lowercase on all three, so in the old days I created an object, set the method to "UpperLower(self)", duplicated it three times, change the object name and I'm done. For simplicity sake, lets say that UpperLower simply do $1->:=Uppercase($1->). How would you do the same while using object notation instead of a variable, dynamic or not?
