--
-- OBJECTIVE:
-- Check that entities and operations declared in a package can be used
-- in the private part of a child of a child of the package.
--
-- TEST DESCRIPTION:
-- Declare a series of library unit packages -- parent, child, and
-- grandchild. The grandchild package will have a private part.
-- From within the private part of the grandchild, make use of
-- components declared in the parent and grandparent packages.
--
-- TEST FILES:
-- The test consists of the following files:

-- CA110050.A
-- => CA110051.AM
