--*
--
-- 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
