-- OBJECTIVE:
-- Check that an access-to-subprogram object can be used to invoke a
-- subprogram when the subprogram body had been declared and implemented
-- as a subunit.
--
-- TEST DESCRIPTION:
-- Declare an access to procedure type in a main program. Declare
-- three different log subprogram body stubs that can be referred to by
-- the access to procedure type.
--
-- Complete bodies of the log procedures.
--
-- In the main program, each procedure will be called indirectly by
-- dereferencing the access value.
--
-- TEST FILES:
-- The following files comprise this test:
--
-- C3A00120.A
-- C3A00121.A
-- => C3A00122.AM

--
-- CHANGE HISTORY:
