   Right.  The name "odd" is available as a user-defined identifier.   
   If you define something named "odd" in Pascal, it hides the   
   predefined function of that name.   
      
   You can think of Pascal's predefined functions as being declared   
   in an outer scope, surrounding the main program.  Pascal's rules   
   for declarations in inner scopes hiding identifiers in outer scopes   
   are similar to C's.   
      
   (C has no predefined functions.)   
      
   If there's more to say about this, I suggest comp.lang.misc or   
   comp.lang.pascal.misc.
