27 -- OBJECTIVE:
28 -- Check that the attributes of modular types yield
29 -- correct values/results. The attributes checked are:
30 --
31 -- First, Last, Range, Base, Min, Max, Succ, Pred,
32 -- Image, Width, Value, Pos, and Val
33 --
34 -- TEST DESCRIPTION:
35 -- This test defines several modular types. One type defined at
36 -- each of System.Max_Binary_Modulus, System.Max_Nonbinary_Modulus,
37 -- a power of two half that of System.Max_Binary_Modulus, one less
38 -- than that power of two; one more than that power of two, two
39 -- less than a (large) power of two. For each of these types,
40 -- determine the correct operation of the following attributes:
41 --
42 -- First, Last, Range, Base, Min, Max, Succ, Pred, Image, Width,
43 -- Value, Pos, Val, and Modulus
44 --
45 -- The attributes Wide_Image and Wide_Value are deferred to C354003.

49 -- CHANGE HISTORY:
50 -- 08 SEP 94 SAIC Initial version
51 -- 17 NOV 94 SAIC Revised version
52 -- 13 DEC 94 SAIC split off Wide_String attributes into C354003
53 -- 06 JAN 95 SAIC Promoted to next release
54 -- 19 APR 95 SAIC Revised in accord with reviewer comments
55 -- 27 JAN 96 SAIC Eliminated 32/64 bit potential conflict for 2.1
