--
-- Grant of Unlimited Rights
--
-- 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
-- any manner and for any purpose whatsoever, and to have or permit others
-- to do so.
--
-- DISCLAIMER
--
-- ALL MATERIALS OR INFORMATION HEREIN RELEASED, MADE AVAILABLE OR
-- DISCLOSED ARE AS IS. THE GOVERNMENT MAKES NO EXPRESS OR IMPLIED
-- WARRANTY AS TO ANY MATTER WHATSOEVER, INCLUDING THE CONDITIONS OF THE

--*
--
-- OBJECTIVE:
-- Check that the default attributes 'Input and 'Output work properly when
-- used with objects of a variety of types, including two-dimensional
-- arrays and records without default discriminants.
--
-- TEST DESCRIPTION:
-- This test simulates utility company service record storage, using
-- Stream_IO to allow the storage of heterogeneous data in a single
-- stream file.
--
-- Three types of data are written to the stream file for each utility
-- service customer.
-- First, the general information on the customer is written.
-- This is an object of a discriminated (without default) record
-- type. This is followed by an integer object containing a count of
-- the number of service months for the customer. Finally, a
-- two-dimensional array object with monthly consumption information for
-- the customer is written to the stream.
--
-- Objects of record types with discriminants without defaults should
-- have their discriminants included in the stream when using 'Output.
-- Likewise, discriminants should be extracted
-- from the stream when using 'Input. Similarly, array bounds are written
-- to and read from the stream when using 'Output and 'Input with array
-- objects.
--
-- APPLICABILITY CRITERIA:
-- Applicable to all implementations that support external
-- Stream_IO files.
--
--
-- CHANGE HISTORY:
-- 06 Dec 94 SAIC ACVC 2.0
