First, THANKS A LOT!!! I've been trying to find a book, or anything that
would say this is how you do it, instead of just blabbing about
polymorphism and how great object oriented stuff is. :)
 
Just one question... it looks like it might be an oversight in your code
ormy lack of understanding of virtual functions...
 
  wv> class Struct1 : public DataStruct { 
  wv>   // define data members here public: 
  wv>   Struct1( FILE *f, int Key ); 
  wv>   virtual ~Struct1(); 
  wv>   virtual void Process(); 
  wv>   virtual void Edit(); 
  wv>   virtual void Save(); } 
  wv> 
  wv> class Struct2 : public DataStruct { 
  wv>   // define data members here public: 
  wv>   Struct2( FILE *f, int Key ); 
  wv>   virtual ~Struct2(); 
  wv>   virtual void Process(); 
  wv>   virtual void Edit(); 
  wv>   virtual void Save(); 
am i right in thinking that the virtual keyword belongs only in the base
class and that the derived classes have no virtual functions (unless
they're bases to another class) ???
