+-- 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 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.
+--

+--
+-- ALL MATERIALS OR INFORMATION HEREIN RELEASED, MADE AVAILABLE OR
+-- DISCLOSED ARE AS IS. THE GOVERNMENT MAKES NO EXPRESS OR IMPLIED

+--*
+--
+-- 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
