Buck,

Consider one or more service programs containing one or more procedures.

You've got a program that takes some input, examines it and determines at run time which procedure
needs to be called. Using the system APIs, it loads the service program resolves a pointer to the
procedure and calls the procedure via the pointer.

That's all polymorphism is basically. The difference when using polymorphism, you don't have to
explicitly handle the determination, resolution, and calling of the appropriate version of the
function.

HTH,
Charles

The basics of OO are available to all of us for
understanding. We just
need to view what we do in the appropriate ways.

I write my own commands all the time, am comfortable with
converting C structures into RPG DS specs and in my vanity, I
like to think I have a handle on the basics of OO.

None of that prepared me for polymorphism. Books with kindly
gentlemen on the cover with examples of animals for classes
just didn't help me out. I don't do enough Java to make that
conceptual leap I guess. I'm not saying that an RPG guy
can't pick up polymorphism the same way I picked up RPG, but
it seems a lot harder.
