26-- OBJECTIVE:
27--      Check that a type derived in a public child inherits primitive
28--      operations from parent.
29--
30-- TEST DESCRIPTION:
31--      Declare a root record type with discriminant in a package
32--      specification. Declare a primitive subprogram for the type
33--      (foundation code).
34--
35--      Add a public child to the above package.  Derive a new type
36--      with constraint to the discriminant record type from the parent
37--      package.  Declare a new primitive subprogram to write to the child
38--      derived type.
39--
40--      Add a new public child to the above package.  This grandchild package
41--      derives a new type using the record type from the above package.
42--      Declare a new primitive subprogram to write to the grandchild derived
43--      type.
44--
45--      In the main program, "with" the grandchild.  Access the inherited
46--      operations from grandparent, parent, and grandchild packages.
47--
48-- TEST FILES:
49--      This test depends on the following foundation code:
