-- 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 --! with Ada.Text_IO; with Report; procedure CXAA007 is use Ada; Inventory_File : Text_IO.File_Type; Inventory_Filename : constant String := Report.Legal_File_Name ( Nam => "CXAA007" ); Incomplete : exception; begin Report.Test ("CXAA007", "Check that the capabilities of " & "Text_IO.Integer_IO operate correctly for files " & "with mode Append_File"); Test_for_Text_IO_Support: begin -- An implementation that does not support Text_IO in a particular -- environment will raise Use_Error on calls to various -- Text_IO operations.
