--
-- 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.
