-- OBJECTIVE:
--     CHECK THAT CONSTRAINT_ERROR IS RAISED IF A VALUE FOR A
--     NON-DISCRIMINANT SCALAR COMPONENT OF AN AGGREGATE IS NOT
--     WITHIN THE RANGE OF THE COMPONENT'S SUBTYPE.
 
-- HISTORY:
--     BCB 01/22/88  CREATED ORIGINAL TEST.
--     RJW 06/27/90  CORRECTED CONSTRAINTS OF TYPE DFIX.
--     LDC 09/25/90  ADDED A BLOCK IN THE EXCEPTION HANDLER SO IT CAN
--                   NOT OPTIMIZE IT AWAY,  ALSO INITIALIZED EACH
--                   OBJECT TO VALID DATA BEFORE DOING THE INVALID,
--                   MADE 'IDENT_XXX' FUNCTIONS SO THE COMPILER CAN
--                   NOT JUST EVALUATE THE ASSIGNMENT AND PUT IN CODE
--                   FOR A CONSTRAINT ERROR IN IS PLACE.
--     JRL 06/07/96  Changed value in aggregate in subtest 4 to value
--                   guaranteed to be in the base range of the type FIX.
--                   Corrected typo.
