A useful note here: all programmers are _used_ to using objects: The file for I/O is an OS-defined object (without the nifty syntax in such cases). OO provides (A) a way to define abstractions that behave like the file abstraction yourself, and (B) a way to (at least sometimes) define an abstaction that is "just like that other abstraction except." Until you have A, B doesn't make sense. B is hard to teach in that you need to go slowly -- the changes made by inheritance take a while to "get." --Scott David Daniels Scott.Daniels@Acm.Org
