-- Unlimited rights are defined in DFAR 252.227-7013(a)(19). By making
-- this public release, the Government intends to confer upon all

-- PARTICULAR PURPOSE OF SAID MATERIAL.
--*
--
-- OBJECTIVE:
-- Check that, for an array aggregate without an others choice assigned
-- to an object of a constrained array subtype, Constraint_Error is not
-- raised if the length of each dimension of the aggregate equals the
-- length of the corresponding dimension of the target object, even if
-- the bounds of the corresponding index ranges do not match.
--
-- TEST DESCRIPTION:
-- The test verifies that sliding of array bounds is performed on array
-- aggregates that are part of a larger aggregate, where the bounds of
-- the corresponding index ranges do not match but the lengths of the
-- corresponding dimensions are the same. Both aggregates containing
-- named associations and positional associations are checked. Cases
-- involving static and nonstatic index constraints, as well as pre-
-- defined and modular integer index subtypes, are included.
--
--
-- CHANGE HISTORY:
-- 15 Apr 96 SAIC Prerelease version for ACVC 2.1.
-- 20 Oct 96 SAIC Removed unnecessary parentheses and type
-- conversions.
