--*
--
-- OBJECTIVE:
--      Check that the Wide_String attributes of modular types yield
--      correct values/results.  The attributes checked are:
--
--      Wide_Image
--      Wide_Value
--
-- TEST DESCRIPTION:
--      This test is split from C354002.  It tests only the attributes:
--
--      Wide_Image, Wide_Value
--
--      This test defines several modular types.  One type defined at
--      each of System.Max_Binary_Modulus, System.Max_Nonbinary_Modulus,
--      a power of two half that of System.Max_Binary_Modulus, one less
--      than that power of two; one more than that power of two, two
--      less than a (large) power of two.  For each of these types,
--      determine the correct operation of the Wide_String attributes.
--
--
-- CHANGE HISTORY:
--      13 DEC 94   SAIC    Initial version
--      06 JAN 94   SAIC    Promoted to future release
--      19 APR 95   SAIC    Revised in accord with reviewer comments
--      01 DEC 95   SAIC    Corrected for 2.0.1
--      27 JAN 96   SAIC    Eliminated potential 32/64 bit conflict for 2.1
--      24 FEB 97   PWB.CTA Corrected out-of-range value
