--                             Grant of Unlimited Rights
--
--     Under contracts F33600-87-D-0337, F33600-84-D-0280, MDA903-79-C-0687,
--     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 
--     this public release, the Government intends to confer upon all 
--     recipients unlimited rights  equal to those held by the Government.  
--     These rights include rights to use, duplicate, release or disclose the 
--     released technical data and computer software in whole or in part, in

--                                    DISCLAIMER
--
--     ALL MATERIALS OR INFORMATION HEREIN RELEASED, MADE AVAILABLE OR
--     DISCLOSED ARE AS IS.  THE GOVERNMENT MAKES NO EXPRESS OR IMPLIED 
--     WARRANTY AS TO ANY MATTER WHATSOEVER, INCLUDING THE CONDITIONS OF THE

--     PARTICULAR PURPOSE OF SAID MATERIAL.
--*
-- CHECK WHETHER A NULL ARRAY WITH ONE DIMENSION OF LENGTH GREATER THAN
-- INTEGER'LAST RAISES CONSTRAINT_ERROR OR NO EXCEPTION,
-- EITHER WHEN DECLARED OR  ASSIGNED.
 
-- CHECK THAT LENGTHS MUST MATCH IN ARRAY AND SLICE ASSIGNMENTS.
--    MORE SPECIFICALLY, TEST THAT ARRAY ASSIGNMENTS WITH MATCHING
--    LENGTHS DO NOT CAUSE  CONSTRAINT_ERROR  TO BE RAISED AND
--    ARE PERFORMED CORRECTLY.
--    (OVERLAPS BETWEEN THE OPERANDS OF THE ASSIGNMENT STATEMENT
--    ARE TREATED ELSEWHERE.)
 
 
-- THIS IS A SPECIAL CASE IN
 
--    DIVISION  D :  NULL ARRAYS WHOSE LENGTHS ARE NOT DETERMINABLE
--                   STATICALLY
 
-- WHICH (THE SPECIAL CASE) TREATS TWO-DIMENSIONAL ARRAYS WHOSE LENGTH
--    ALONG ONE DIMENSION IS GREATER THAN  INTEGER'LAST  AND WHOSE
--    LENGTH ALONG THE OTHER DIMENSION IS  0 .
 
 
-- *** NOTE: This test has been modified since ACVC version 1.11 to    -- 9X
-- ***       remove incompatibilities associated with the transition   -- 9X
-- ***       to Ada 9X.                                                -- 9X
-- ***                                                                 -- 9X
 
-- RM  07/31/81
-- SPS 03/22/83
-- JBG 05/02/83
-- JBG 06/01/85
-- EG  10/28/85  FIX NUMERIC_ERROR/CONSTRAINT_ERROR ACCORDING TO
--               AI-00387.
-- LDC 06/01/88  CHANGED HEADER COMMENT TO INDICATE CONSTRAINT_ERROR
--               IS ALLOWED.  ADDED CODE TO PREVENT DEAD VARIABLE
--               OPTIMIZATION.
-- MRM 03/30/93  REMOVED NUMERIC_ERROR FOR 9X COMPATIBILITY
