Declare a +-- library-level generic subprogram with a formal derived type using the +-- record type as ancestor. Give the generic subprogram an in out +-- parameter of the formal derived type. Inside the generic, use the +-- discriminant component and modify the remaining components of the +-- record parameter. In the main program, declare record objects with two +-- different discriminant values. Derive an indefinite type from the +-- record type with a new discriminant part. Instantiate the generic +-- subprogram for the root record subtype and the derived subtype. Call +-- the root subtype instance with actual parameters having the two +-- discriminant values. Also call the derived subtype instance with +-- an appropriate actual. +-- +-- +-- CHANGE HISTORY: +-- 06 Dec 94 SAIC ACVC 2.0 +-- 03 Jan 95 SAIC Removed unknown discriminant part from formal +-- derived type. +-- 05 Nov 95 SAIC ACVC 2.0.1 fixes: Removed constrained subtype +-- instantiation and associated declarations. +-- Modified commentary. +-- +--! + + +-- Simulate a fragment of a matrix manipulation application. + +package CC51003_0 is -- Matrix types. + + type Matrix is array (Natural range <>, Natural range <>) of Integer; + + type Square (Side : Natural) is record + Mat : Matrix (1 ..
