-- CHECK THAT LENGTHS MUST MATCH IN ARRAY AND SLICE ASSIGNMENTS.
--    MORE SPECIFICALLY, TEST THAT ATTEMPTED ASSIGNMENTS BETWEEN
--    ARRAYS WITH NON-MATCHING LENGTHS LEAVE THE DESTINATION ARRAY
--    INTACT AND CAUSE  CONSTRAINT_ERROR  TO BE RAISED.
--    (OVERLAPS BETWEEN THE OPERANDS OF THE ASSIGNMENT STATEMENT
--    ARE TREATED ELSEWHERE.)

-- THIS IS A SPECIAL CASE IN

--    DIVISION  C :  NON-NULL ARRAYS WHOSE LENGTHS ARE NOT DETERMINABLE
--                   STATICALLY

-- WHICH TREATS ARRAYS OF LENGTH GREATER THAN  INTEGER'LAST .
--    AN ADDITIONAL OBJECTIVE OF THIS TEST IS TO CHECK WHETHER LENGTH
--    COMPARISONS (AND LENGTH COMPUTATIONS) CAUSE
--    CONSTRAINT_ERROR TO BE RAISED.

-- *** NOTE: This test has been modified since ACVC version 1.11 to    -- 9X
-- ***       remove incompatibilities associated with the transition   -- 9X
