+--*
+--
+-- OBJECTIVE:
+--      Check that the use of 'Class'Output and 'Class'Input allow stream 
+--      manipulation of objects of non-limited class-wide types.
+--
+-- TEST DESCRIPTION:
+--      This test demonstrates the uses of 'Class'Output and 'Class'Input
+--      in moving objects of a particular class to and from a stream file.
+--      A procedure uses a class-wide parameter to move objects of specific 
+--      types in the class to the stream, using the 'Class'Output attribute 
+--      of the root type of the class.  A function returns a class-wide object, 
+--      using the 'Class'Input attribute of the root type of the class to 
+--      extract the object from the stream.
+--      A field-by-field comparison of record objects is performed to validate
+--      the data read from the stream.  Operator precedence rules are used
+--      in the comparison rather than parentheses.
+--      
+-- APPLICABILITY CRITERIA: 
+--      This test is applicable to all implementations capable of supporting
+--      external Stream_IO files.
+--
+--
+-- CHANGE HISTORY:
+--      06 Dec 94   SAIC    ACVC 2.0
+--      14 Nov 95   SAIC    Corrected prefix of 'Tag attribute for ACVC 2.0.1.
+--      24 Aug 96   SAIC    Changed a call to "Create" to "Reset".
+--      26 Feb 97   CTA.PWB Allowed for non-support of some IO operations.
