Check that the +-- visible part of the generic formal package includes the first list of +-- basic declarative items of the package specification. +-- +-- TEST DESCRIPTION: +-- A generic formal package is a package, and is an instance. +-- +-- Declare a list type in a generic package for lists of elements of any +-- nonlimited type (foundation code). Declare a second generic package +-- which declares operations for the list type, and parameterize it with +-- a generic formal package with the list-type package as template +-- (foundation code). Declare a third generic package which declares +-- additional operations for the list type, and parameterize it with two +-- generic formal packages, one with the list-type package as template, +-- the other with the second generic package as template. Use the first +-- formal package as the generic formal actual part for the second formal +-- package. +-- +-- TEST FILES: +-- The following files comprise this test: +-- +-- FC70C00.A +-- CC70C02.A +-- +-- +-- CHANGE HISTORY: +-- 06 Dec 94 SAIC ACVC 2.0 +-- +--! + +with FC70C00_0; -- List abstraction. +with FC70C00_1; -- Basic list operations. +generic + + -- Import both the list-type abstraction defined in FC70C00_0 and the basic + -- list operations defined in FC70C00_1.
