-- 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.
