+--*
+--
+-- OBJECTIVE:
+-- Check that Ada.Text_IO.Editing.Put and Ada.Text_IO.Put have the same
+-- effect.
+--
+-- 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 testing approach used in this test is that of writing edited
+-- output data to a text file, using two different approaches. First,
+-- Ada.Text_IO.Put is used, with a call to an instantiated version of
+-- Function Image supplied as the actual for parameter Item. The
+-- second approach is to use a version of Function Put from an
+-- instantiation of Ada.Text_IO.Editing.Decimal_Output, with the
+-- appropriate parameters for decimal data, picture, and format
+-- specific parameters. A call to New_Line follows each Put, so that
+-- each entry is placed on a separate line in the text file.
+--
+-- Edited output for decimal data with two decimal places is in the
+-- first loop, and once the data has been written to the file, the
+-- text file is closed, then opened in In_File mode. The edited
+-- output data is read from the file, and data on successive lines
+-- is compared with the expected edited output result. The edited
+-- output data produced by both of the Put procedures should be
+-- identical.
+--
+-- This process is repeated for decimal data with no decimal places.
+-- The file is reopened in Append_File mode, and the edited output
+-- data is added to the file in the same manner as described above.
+-- The file is closed, and reopened to verify the data written.
+-- The data written above (with two decimal places) is skipped, then
+-- the data to be verified is extracted as above and verified against
+-- the expected edited output string values.
+--
+-- APPLICABILITY CRITERIA:
+-- This test is applicable only to implementations that support
+-- external text files.
+--
+-- TEST FILES:
+-- The following files comprise this test:
+--
+-- FXF3A00.A (foundation code)
+-- => CXF3A06.A
+--
+--
+-- CHANGE HISTORY:
+-- 26 JAN 95 SAIC Initial prerelease version.
+-- 26 FEB 97 PWB.CTA Made input buffers sufficiently long
+-- and removed code depending on shorter buffers
