Because, my intention is to build an interface that many other objects could implement. Then polymorphism allows you to use the defined interface with any of the subclasses. It's a fairly essential part of producing reusable object oriented code. I can of course still make the interface but I have to add a useless attribute when I build the object (dummy char(1)). I was hoping someone would have done this before and be able to suggest a better workaround.
