--
-- OBJECTIVE
-- Check that an others choice is allowed in an array aggregate whose
-- applicable index constraint is dynamic. (This was an extension to
-- Ada 83). Check that index choices are within the applicable index
-- constraint for array aggregates with others choices.
--
-- TEST DESCRIPTION
-- In this test, we declare several unconstrained array types, and
-- several dynamic subtypes. We then test a variety of cases of using
-- appropriate aggregates. Some cases expect to raise Constraint_Error.

-- HISTORY:
-- 16 DEC 1999 RLB Initial Version.
