-- OBJECTIVE:
--     CHECK THAT IN MULTIPLE OBJECT DECLARATIONS FOR ARRAY TYPES, THE
--     SUBTYPE INDICATION AND THE INITIALIZATION EXPRESSIONS ARE
--     EVALUATED ONCE FOR EACH NAMED OBJECT THAT IS DECLARED AND THE
--     SUBTYPE INDICATION IS EVALUATED FIRST.  ALSO, CHECK THAT THE
--     EVALUATIONS YIELD THE SAME RESULT AS A SEQUENCE OF SINGLE OBJECT
--     DECLARATIONS.

-- HISTORY:
--     RJW 07/16/86  CREATED ORIGINAL TEST.
--     BCB 08/18/87  CHANGED HEADER TO STANDARD HEADER FORMAT.  CHANGED
--                   COMMENTS FOR S4 AND CS4 TO READ THAT THE BOUNDS ARE
--                   1 .. 6 AND THE COMPONENT TYPE ARR IS 1 .. 5.
