--
-- 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.
