Oh, sigh -- let me try again.  This:

   IF ( ( ptr = NIL ) OR ELSE ( ptr^.intval <> 0 ) ) THEN
      { statements }

is the same as this:

   IF ( ptr = NIL ) THEN
      { statements }
   ELSE IF ( ptr^.intval <> 0 ) THEN
      { statements }

Read the manual for details.  (Do what I mean, not what I say. :)
