+--*
+--
+-- OBJECTIVE:
+--      Check that the procedures New_Page, Set_Line, Set_Col, and New_Line
+--      subprograms perform properly on a text file reset (from Out_File) 
+--      with mode Append_File.
+--      Check that the attributes Page, Line, and Column are all set to 1
+--      following the reset of a text file with mode Append_File.
+--      Check that the functions Page, Line, and Col perform properly on a
+--      text file reset with mode Append_File.
+--      Check that the procedures Put and Put_Line perform properly on text
+--      files reset with mode Append_File.
+--      Check that the procedure Set_Line sets the current line number to
+--      the value specified by the parameter "To" for text files reset with
+--      mode Append_File.  Check that Set_Line has no effect if the specified
+--      line equals the current line.
+--      Check that the procedure Set_Col sets the current column number to
+--      the value specified by the parameter "To" for text files reset with
+--      mode Append_File.
+--
+-- TEST DESCRIPTION:
+--      This test is designed to simulate the text processing that could
+--      occur with files that have been created in Out_File mode,
+--      and then reset to Append_File mode. 
+--      Various calls to Text_IO formatting subprograms are called to properly
+--      position text appended to a document.  The text content and position
+--      are subsequently verified for accuracy.
+--
+-- APPLICABILITY CRITERIA: 
+--      This test is applicable only to implementations that support text
+--      files.
+--
+--       
+-- CHANGE HISTORY:
+--      06 Dec 94   SAIC    ACVC 2.0
+--      24 Feb 97   PWB.CTA Allowed for non-support of some IO operations.
