System messages are created by +-- instantiating the generic with a system message type derived from the +-- root in a separate package. The system message type has a primitive +-- subprogram called Send. +-- +-- Inside the generic, a "mail" type is derived from the generic formal +-- derived type, and a "Send" operation is declared. +-- +-- Declare a root tagged type T. Declare a generic package with a formal +-- derived type using the root tagged type as ancestor. In the generic, +-- derive a type from the formal derived type and declare a primitive +-- subprogram for it. In a separate package, declare a derivative DT of +-- the root tagged type T and declare a primitive subprogram which is +-- type conformant with (and hence, overridable for) the primitive +-- declared in the generic. Instantiate the generic for DT. Make both +-- dispatching and non-dispatching calls to the primitive subprogram. In +-- both cases the version of the subprogram in the instance should be +-- called (since it overrides the implementation inherited from the +-- actual). +-- +-- +-- CHANGE HISTORY: +-- 06 Dec 94 SAIC ACVC 2.0 +-- 13 Apr 95 SAIC Replaced call involving instance for root tagged +-- type with a dispatching call involving instance +-- for derived type. Updated commentary.
