--

-- 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.
