Now this is the first real objection to my statement: OS/2 and the Presentation Manager, or windowing system. But, here it is significant that the user /consumer (i.e. *at the workstation* mind you) is *making* the "object" because thier visual system turns it into one. Otherwise, at the C-level, I'm guessing it's normal C code without objects, only struct-ured data. That is, you don't get all the OOP benefits like inheritance, polymorphism and encapsulation. C can do 2 of those, albeit kludgingly, but not all three. And without all three, it's not at all well-established that you're doing real OOP. -- MarkJ Tacoma, Washington -- https://mail.python.org/mailman/listinfo/python-list
