-- OBJECTIVE:
--     CHECK THAT THE ATTRIBUTES 'IMAGE' AND 'VALUE YIELD THE CORRECT
--     RESULTS WHEN THE PREFIX IS A FORMAL DISCRETE TYPE WHOSE ACTUAL
--     PARAMETER IS A CHARACTER TYPE.
--     SUBTESTS ARE:
--         (A). TESTS FOR IMAGE.
--         (B). TESTS FOR VALUE.
 
-- HISTORY:
--     RJW  05/29/86  CREATED ORIGINAL TEST.
--     VCL  10/23/87  MODIFIED THIS HEADER, CHANGED THE CALLS TO
--                    PROCEDURE 'PCH', IN THE SECOND PART OF SUBTEST B,
--                    TO INCLUDE ANOTHER CALL TO PROCEDURE 'PCHAR' AND
--                    CALLS TO PROCEDURE 'PNCHAR'.
