Declare a +-- library-level generic subprogram with a formal derived type using the +-- tagged 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 +-- tagged parameter. In the main program, declare tagged record objects +-- with two different discriminant values. Derive an indefinite type from +-- the tagged type with a new discriminant part. Instantiate the +-- generic subprogram for the root tagged 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 +-- 05 Jan 94 SAIC Removed unknown discriminant part from formal +-- derived type.
