   Hi Everyone!   
      
   I'm designing a Pascal grammar for Gepsoft APS 4.0 and I'm yet to decide if   
   I'll adopt the handy notation used in freepascal for the exclusive or (a xor   
   b) or if I should use a user defined xor in order to make the grammar more   
   universal. Your thoughts on that will be greatly appreciated.   
      
   Cheers,
