-- Unlimited rights are defined in DFAR 252.227-7013(a)(19). By making
-- this public release, the Government intends to confer upon all
-- recipients unlimited rights equal to those held by the Government.

-- DISCLAIMER

--
-- OBJECTIVE:
-- Check that the attributes of modular types yield
-- correct values/results. The attributes checked are:
--
-- First, Last, Range, Base, Min, Max, Succ, Pred,
-- Image, Width, Value, Pos, and Val
--
-- TEST DESCRIPTION:
-- 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 following attributes:
--
-- First, Last, Range, Base, Min, Max, Succ, Pred, Image, Width,
-- Value, Pos, Val, and Modulus
--
-- The attributes Wide_Image and Wide_Value are deferred to C354003.
--
--
--
-- CHANGE HISTORY:
-- 08 SEP 94 SAIC Initial version
-- 17 NOV 94 SAIC Revised version
-- 13 DEC 94 SAIC split off Wide_String attributes into C354003
-- 06 JAN 95 SAIC Promoted to next release
-- 19 APR 95 SAIC Revised in accord with reviewer comments
-- 27 JAN 96 SAIC Eliminated 32/64 bit potential conflict for 2.1
