-- CXAA007.A
--
-- 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
-- SOFTWARE, DOCUMENTATION OR OTHER INFORMATION RELEASED, MADE AVAILABLE
-- OR DISCLOSED, OR THE OWNERSHIP, MERCHANTABILITY, OR FITNESS FOR A
-- PARTICULAR PURPOSE OF SAID MATERIAL.
--*
--
-- OBJECTIVE:
-- Check that the capabilities of Text_IO.Integer_IO perform correctly
-- on files of Append_File mode, for instantiations with integer and
-- user-defined subtypes.
-- Check that the formatting parameters available in the package can
-- be used and modified successfully in the storage and retrieval of
-- data.
--
-- TEST DESCRIPTION:
-- This test simulates a receiving department inventory system. Data on
-- items received is entered into an inventory database. This information
-- consists of integer entry number, item number, and bar code.
-- One item is placed into the inventory file immediately following file
-- creation, subsequent items are entered following file opening in
-- Append_File mode. Data items are validated by reading all data from
-- the file and comparing against known values (those used to enter the
-- data originally).
--
-- This test verifies issues of create in Append_File mode, appending to
-- a file previously appended to, opening in Append_File mode, resetting
-- from Append_File mode to In_File mode, as well as a variety of Text_IO
-- and Integer_IO predefined subprograms.
--
-- APPLICABILITY CRITERIA:
-- This test is applicable only to implementations that support text
-- files.
--
--
-- CHANGE HISTORY:
-- 06 Dec 94 SAIC ACVC 2.0
-- 25 Feb 97 PWB.CTA Allowed for non-support of some IO operations
--!
