 This is a rather trivial question on Prolog.
 
  I have Prolog system 2.0 running on an Explorer II and at
  the query prompt, I type the following:
 
  ?- [user].<RETURN>
  | likes(john,mary).<RETURN>
  | ?-likes(john,X).<RETURN>
  | No
 
  I cant see why a simple program as that is not working.
  Can some one say whats the problem here?
 
  Thanks
  Raghu
