26 -- OBJECTIVE:
27 -- Check that if the ancestor type of a formal derived type is a composite
28 -- type that is not an array type, the formal type inherits components,
29 -- including discriminants, from the ancestor type.
30 --
31 -- Check for the case where the ancestor type is a tagged type, and the
32 -- formal derived type is declared in a generic subprogram.
33 --
34 -- TEST DESCRIPTION:
35 -- Define a discriminated tagged type in a package. Declare a
36 -- library-level generic subprogram with a formal derived type using the
37 -- tagged type as ancestor. Give the generic subprogram an in out
38 -- parameter of the formal derived type. Inside the generic, use the
39 -- discriminant component and modify the remaining components of the
40 -- tagged parameter. In the main program, declare tagged record objects
41 -- with two different discriminant values. Derive an indefinite type from
42 -- the tagged type with a new discriminant part. Instantiate the
43 -- generic subprogram for the root tagged subtype and the derived subtype.
44 -- Call the root subtype instance with actual parameters having the two
45 -- discriminant values. Also call the derived subtype instance with an
46 -- appropriate actual.

49 -- CHANGE HISTORY:
50 -- 06 Dec 94 SAIC ACVC 2.0
51 -- 05 Jan 94 SAIC Removed unknown discriminant part from formal
52 -- derived type. Moved declaration of type
53 -- New_Dbl_Sq from main subprogram to CC51004_0.
54 -- 05 Nov 95 SAIC ACVC 2.0.1 fixes: Removed constrained subtype
55 -- instantiation and associated declarations.
56 -- Modified commentary.
