-- OBJECTIVE:
-- Check that an object of a task interface type can be the prefix of the
-- Terminated and Callable attributes.
--
-- Check that an object of a task interface type can be passed to an
-- abort statement.
--
-- CHANGE HISTORY:
-- 20 Oct 2005 HK Initial Version
-- 05 Dec 2005 HK Add delays to ensure uniform output on different
-- machines.
-- 28 Oct 2007 RLB Corrected objective, made self-testing, renamed
-- for ACATS 3.0.
