-- F08630-91-C-0015, and DCA100-97-D-0025, the U.S. Government obtained
-- unlimited rights in the software and documentation contained herein.
-- Unlimited rights are defined in DFAR 252.227-7013(a)(19). By making

--*
-- 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.
