-- CXB4006.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 function Valid with Packed_Decimal and Packed_Format
-- parameters returns True if Item (the Packed_Decimal parameter) has
-- a value consistent with the Packed_Format parameter.
--
-- Check that the function Length with Packed_Format parameter returns
-- the minimal length of a Packed_Decimal value sufficient to hold any
-- value of type Num when represented according to parameter Format.
--
-- Check that the function To_Decimal with Packed_Decimal and
-- Packed_Format parameters produces a decimal type value corresponding
-- to the Packed_Decimal parameter value Item, under the conditions of
-- the Packed_Format parameter Format.
--
-- Check that the function To_Packed with Decimal (Num) and
-- Packed_Format parameters produces a Packed_Decimal result that
-- corresponds to the decimal parameter under conditions of the
-- Packed_Format parameter.
--
-- Check that Conversion_Error is propagated by function To_Packed if
-- the value of the decimal parameter Item is negative and the specified
-- Packed_Format parameter is Packed_Unsigned.
--
--
-- TEST DESCRIPTION:
-- This test checks the results from instantiated versions of
-- several functions that deal with parameters or results of type
-- Packed_Decimal. Since the rules for the formation of Packed_Decimal
-- values are implementation defined, several of the subtests cannot
-- directly check the accuracy of the results produced. Instead, they
-- verify that the result is within a range of possible values, or
-- that the result of one function can be converted back to the original
-- actual parameter using a "mirror image" conversion function.
--
-- APPLICABILITY CRITERIA:
-- This test is applicable to all implementations that provide
-- package Interfaces.COBOL. If an implementation provides
-- package Interfaces.COBOL, this test must compile, execute, and
-- report "PASSED".
--
--
-- CHANGE HISTORY:
-- 12 Feb 96 SAIC Initial release for 2.1.
-- 30 May 96 SAIC Incorporated reviewer comments for ACVC 2.1.
-- 27 Oct 96 SAIC Incorporated reviewer comments.
