-- These rights include rights to use, duplicate, release or disclose the

--
-- DISCLAIMER
--
-- ALL MATERIALS OR INFORMATION HEREIN RELEASED, MADE AVAILABLE OR
-- DISCLOSED ARE AS IS. THE GOVERNMENT MAKES NO EXPRESS OR IMPLIED
-- WARRANTY AS TO ANY MATTER WHATSOEVER, INCLUDING THE CONDITIONS OF THE

--*
--
-- OBJECTIVE:
-- Check that a record extension can be declared in the same package
-- as its parent, and that this parent may be a tagged record or a
-- record extension. Check that each derivative inherits all user-
-- defined primitive subprograms of its parent (including those that
-- its parent inherited), and that it may declare its own primitive
-- subprograms.
--
-- Check that predefined equality operators are defined for the root
-- tagged type.
--
-- Check that type conversion is defined from a type extension to its
-- parent, and that this parent itself may be a type extension.
--
-- TEST DESCRIPTION:
-- Declare a root tagged type in a package specification. Declare two
-- primitive subprograms for the type.
--
-- Extend the root type with a record extension in the same package
-- specification. Declare a new primitive subprogram for the extension
-- (in addition to its two inherited subprograms).
--
-- Extend the extension with a record extension in the same package
-- specification. Declare a new primitive subprogram for this second
-- extension (in addition to its three inherited subprograms).
--
-- In the main program, declare operations for the root tagged type which
-- utilize aggregates and equality operators to verify the correctness
-- of the components. Overload these operations for the two type
-- extensions. Within each of these overloading operations, utilize type
-- conversion to call the parent's implementation of the same operation.

-- The following files comprise this test:
