Thanks to all who replied for their suggestions of examples. I have looked
at these and now have a better
understanding of polymorphism.
I think my main problem was getting around the fact that in C++,
polymorphism is achieved through
virtual functions and using a pointer or reference to a base class. In
Ada95, polymorphism can be
achieved with normal (non-pointer) types. It is using the class wide type
that is crucial.
Thanks again.
