  I am still a little confused about how to use the object extensions in 
Turbo Pascal.  I have Turbo Pascal 5.5. and wrote a paper "Oops Defined"
see Comp.object.  However, I still can't seem to make anything work with
objects.  What I would like to do is make a window I have in a program
updatable.  Would you be so kind as to send me any suggestions and 
examples of object oriented programs in Turbo Pascal?  A basic skeleton
using some of the "objects" included in TP5.5 would be good.  Does anybody
have a window object with scroll bars and such?  If the window works 
with common ascii text files it would be enough.
  Does anybody really understand OOPS?  Why are there five definitions to 
polymorphism?  Why is a type in one OOPS language = a class in another?
How is inheretance implemented (examples please) in TP5.5 ?
