Check that the formal type may be extended with +-- a record extension in the generic package. +-- +-- Check that, in the instance, the record extension inherits the +-- user-defined primitive subprograms of the tagged actual. +-- +-- TEST DESCRIPTION: +-- Declare a tagged type and an associated primitive subprogram in a +-- package specification (foundation code). Declare a generic package +-- which takes a tagged type as a formal parameter, and then extends +-- it with a record extension (foundation code). +-- +-- Instantiate the generic package with the tagged type from the first +-- package (the "generic" extension should now have inherited +-- the primitive subprogram of the tagged type from the first +-- package). +-- +-- In the main program, call the primitive subprogram inherited by the +-- "generic" extension, and verify the correctness of the components. +-- +-- TEST FILES: +-- This test consists of the following files: +-- +-- F340A000.A +-- F340A001.A +-- => C340A01.A +-- +-- +-- CHANGE HISTORY: +-- 06 Dec 94 SAIC ACVC 2.0 +-- 12 Jun 96 SAIC ACVC 2.1: Modified prologue.
