-- Under contracts F33600-87-D-0337, F33600-84-D-0280, MDA903-79-C-0687,
-- F08630-91-C-0015, and DCA100-97-D-0025, the U.S. Government obtained
-- unlimited rights in the software and documentation contained herein.
-- Unlimited rights are defined in DFAR 252.227-7013(a)(19). By making
-- this public release, the Government intends to confer upon all
-- recipients unlimited rights equal to those held by the Government.
-- These rights include rights to use, duplicate, release or disclose the
-- released technical data and computer software in whole or in part, in

-- DISCLAIMER
--
-- ALL MATERIALS OR INFORMATION HEREIN RELEASED, MADE AVAILABLE OR

--*
--
-- OBJECTIVE:
-- Check that a predefined exception is correctly propagated out of a
-- public child function to a client.
--
-- TEST DESCRIPTION:
-- Declare a public child subprogram. Define the processing loop
-- inside the subprogram to expect a string with index starting at 1.
-- From the test procedure, call the child subprogram with a slice
-- from the middle of a string variable. This will cause an exception
-- to be raised in the child and propagated to the caller.
--
-- Exception Type Raised:
-- User Defined
-- * Predefined
--
-- Hierarchical Structure Employed For This Test:
-- * Parent Package
-- Public Child Package
-- Private Child Package
-- * Public Child Subprogram
-- Private Child Subprogram
--
-- TEST FILES:
-- This test depends on the following foundation code:
-- FB40A00.A
--
--
-- CHANGE HISTORY:
-- 06 Dec 94 SAIC ACVC 2.0
--
--!
-- Child subprogram Text_Parser.Count_AlphaNumerics

end if;
end loop;
return (AlphaNumeric_Count); -- Global in parent package.
-- No exception handler here, exception propagates.
