--     CHECK THAT THE 'RANGE ATTRIBUTE CAN BE USED TO DECLARE OBJECTS
--     AND IN A SUBTYPE AND TYPE DECLARATION.

-- HISTORY:
--     LB  08/13/86  CREATED ORIGINAL TEST.
--     BCB 08/18/87  CHANGED HEADER TO STANDARD HEADER FORMAT.
--                   REARRANGED STATEMENTS SO TEST IS CALLED FIRST.
--                   ELIMINATED DEAD VARIABLE OPTIMIZATION.  CHECKED
--                   RANGE VALUES FOR A SMALL INTEGER.
