--
-- 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 function Length, with Display_Format parameter, will
-- return the minimal length of a Numeric value that will be required
-- to hold the largest value of type Num represented as Format.
--
-- Check that function To_Decimal will produce a decimal type Num
-- result that corresponds to parameter Item as represented by
-- parameter Format.
--
-- Check that function To_Decimal propagates Conversion_Error when
-- the value represented by parameter Item is outside the range of
-- the Decimal_Type Num used to instantiate the package
-- Decimal_Conversions
--
-- Check that function To_Display returns a Numeric type result that
-- represents Item under the specific Display_Format.
--
-- Check that function To_Display propagates Conversion_Error when
-- parameter Item is negative and the specified Display_Format
-- parameter is Unsigned.
--
-- TEST DESCRIPTION:
-- This test checks the results from instantiated versions of three
-- functions within generic package Interfaces.COBOL.Decimal_Conversions.
-- This generic package is instantiated twice, with decimal types having
-- four and ten digits representation.
-- The function Length is validated with the Unsigned, Leading_Separate,
-- and Trailing_Separate Display_Format specifiers.
-- The results of function To_Decimal are verified in cases where it
-- is given a variety of Numeric and Display_Format type parameters.
-- Function To_Decimal is also checked to propagate Conversion_Error
-- when the value represented by parameter Item is outside the range
-- of the type used to instantiate the package.
-- The results of function To_Display are verified in cases where it
-- is given a variety of Num and Display_Format parameters. It is also
-- checked to ensure that it propagates Conversion_Error if parameter
-- Num is negative and the Format parameter is Unsigned.
--
-- This test assumes that the following characters are all included
-- in the implementation defined type Interfaces.COBOL.COBOL_Character:
-- ' ', '0'..'9', '+', '-', and '.'.
--
-- 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:
-- 06 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.
