-- OBJECTIVE:
--     CHECK THAT WHEN SIZE AND SMALL SPECIFICATIONS ARE GIVEN FOR A
--     FIXED POINT TYPE, THEN OPERATIONS ON VALUES OF SUCH A TYPE ARE
--     NOT AFFECTED BY THE REPRESENTATION CLAUSE.

-- APPLICABILITY CRITERIA:
--      All implementations must attempt to compile this test.
--
--      For implementations validating against Systems Programming Annex (C)
--          and which support decimal small values:
--          The test must compile, bind, execute, report PASSED, and
--          complete normally.
--
--      For other implementations:
--          This test may produce at least one error message at compilation,
--          and the error message is associated with one of the items marked:
--             -- N/A => ERROR.
--          The test will be recorded as Not_Applicable.
--          Otherwise, the test must execute and report PASSED.
--
--      All other behaviors are FAILING.
--
-- HISTORY:
--     BCB 08/24/87  CREATED ORIGINAL TEST.
--     DHH 04/12/89  CHANGED EXTENSION FROM '.DEP' TO '.ADA', CHANGED
--                   OPERATORS ON 'SIZE TESTS, AND CHANGED 'SIZE CLAUSE
--                   SO THAT IT IS NOT A POWER OF TWO.
--     WMC 04/01/92  ELIMINATED TEST REDUNDANCIES.
--     RLB 11/24/98  Added Ada 95 applicability criteria.
