-- These rights include rights to use, duplicate, release or disclose the

--*
--
-- OBJECTIVE:
-- Check that the edited output string value returned by Function Image
-- is correct.
--
-- TEST DESCRIPTION:
-- This test is structured using tables of data, consisting of
-- numerical values, picture strings, and expected image
-- result strings. These data tables are found in package FXF3A00.
--
-- The results of the Image function are examined under a number of
-- circumstances. The generic package Decimal_Output is instantiated
-- twice, for decimal data with delta 0.01 and delta 1.0. Each version
-- of Image is called with both default parameters and user-provided
-- parameters. The results of each call to Image are compared to an
-- expected edited output result string.
--
-- In addition, three calls to Image are designed to raise Layout_Error,
-- due to the combination of decimal value and picture string provided
-- as input parameters. If Layout_Error is not raised, or an alternate
-- exception is raised instead, test failure results.
--
-- TEST FILES:
-- The following files comprise this test:
--
-- FXF3A00.A (foundation code)
-- => CXF3A04.A
--
--
-- CHANGE HISTORY:
-- 22 JAN 95 SAIC Initial prerelease version.
-- 11 MAR 97 PWB.CTA Corrected incorrect index expression
--!
