+--*
+--
+-- 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.
