however, a bit diferent in that they are alomost OO in nature. The Create
private error simply means that the Superclass has a method to create itself.
This is a mechanism to control the creation of classes. You will find that the
superclass will have a method to allow creation. Simply call this method and it
will return, most likely, a reference to the object you need.</span></font><o:p></o:p></p>

are private to the superclass and you cannot use them. You should really not
need to if the superclass has been designed correctly - you will probably find
that they can be accessed via methods. If you copy the class you can change
anything but this is more than likely not the way to go.</span></font><o:p></o:p></p>
