--
--     Under contracts F33600-87-D-0337, F33600-84-D-0280, MDA903-79-C-0687,

--*
-- OBJECTIVE:
--     CHECK, WHERE AN INDEX CONSTRAINT DEPENDS ON A RECORD
--     DISCRIMINANT WITH A DEFAULT VALUE AND THE RECORD TYPE IS NOT
--     EXPLICITLY CONSTRAINED, THAT THE NON-DISCRIMINANT EXPRESSIONS
--     IN THE INDEX CONSTRAINT ARE:
--          1) EVALUATED WHEN THE RECORD COMPONENT SUBTYPE DEFINITION
--             IS ELABORATED,
--          2) PROPERLY CHECKED FOR COMPATIBILITY ONLY IN AN ALLOCATION
--             OR OBJECT DECLARATION AND ONLY IF THE DISCRIMINANT-
--             DEPENDENT COMPONENT IS PRESENT IN THE SUBTYPE.
 
-- HISTORY:
--     JBG  10/17/86  CREATED ORIGINAL TEST.
--     VCL  10/23/87  MODIFIED THIS HEADER; MODIFIED THE CHECK OF
--                    SUBTYPE 'SCONS', IN BOTH SUBPARTS OF THE TEST,
--                    TO INDICATE FAILURE IF CONSTRAINT_ERROR IS RAISED
--                    FOR THE SUBTYPE DECLARATION AND FAILURE IF
--                    CONSTRAINT_ERROR IS NOT RAISED FOR AN OBJECT
--                    DECLARATION OF THIS SUBTYPE; RELOCATED THE CALL TO
--                    REPORT.TEST SO THAT IT COMES BEFORE ANY
--                    DECLARATIONS;  ADDED 'SEQUENCE_NUMBER' TO IDENTIFY
--                    THE CURRENT SUBTEST (FOR EXCEPTIONS); CHANGE THE
--                    TYPE OF THE DISCRIMINANT IN THE RECORD 'CONS'
--                    TO AN INTEGER SUBTYPE.
--     VCL  03/30/88  MODIFIED HEADER AND MESSAGES OUTPUT BY REPORT
--                    PACKAGE.
