Various subprograms are defined to fit the profile +-- of this access type, such that the record component can refer to +-- any of the subprograms. +-- +-- Each of the subprograms raises a different exception, based on the +-- value of an input parameter. Exceptions are 1) raised, handled with +-- an others handler, reraised and propagated to main to be handled in +-- a specific handler; 2) raised, handled in a specific handler, reraised +-- and propagated to the main to be handled in an others handler there, +-- and 3) raised and propagated directly to the caller by the subprogram. +-- +-- Boolean variables are set throughout the test to ensure that correct +-- exception processing has occurred, and these variables are verified at +-- the conclusion of the test. +-- +-- +-- CHANGE HISTORY: +-- 06 Dec 94 SAIC ACVC 2.0 +-- +--! + +package CB20003_0 is -- package Push_Buttons + + + Non_Default_Priority, + Non_Alert_Priority, + Non_Emergency_Priority : exception;
