  25 -- OBJECTIVE:
  26 --     CHECK THAT WHEN SIZE AND SMALL SPECIFICATIONS ARE GIVEN FOR A
  27 --     FIXED POINT TYPE, THEN OPERATIONS ON VALUES OF SUCH A TYPE ARE
  28 --     NOT AFFECTED BY THE REPRESENTATION CLAUSE.
  29
  30 -- APPLICABILITY CRITERIA:
  31 --      All implementations must attempt to compile this test.
  32 --
  33 --      For implementations validating against Systems Programming Annex (C)
  34 --          and which support decimal small values:
  35 --          The test must compile, bind, execute, report PASSED, and
  36 --          complete normally.
  37 --
  38 --      For other implementations:
  39 --          This test may produce at least one error message at compilation,
  40 --          and the error message is associated with one of the items marked:
  41 --             -- N/A => ERROR.
  42 --          The test will be recorded as Not_Applicable.
  43 --          Otherwise, the test must execute and report PASSED.
  44 --
  45 --      All other behaviors are FAILING.
  46 --
  47 -- HISTORY:
  48 --     BCB 08/24/87  CREATED ORIGINAL TEST.
  49 --     DHH 04/12/89  CHANGED EXTENSION FROM '.DEP' TO '.ADA', CHANGED
  50 --                   OPERATORS ON 'SIZE TESTS, AND CHANGED 'SIZE CLAUSE
  51 --                   SO THAT IT IS NOT A POWER OF TWO.
  52 --     WMC 04/01/92  ELIMINATED TEST REDUNDANCIES.
  53 --     RLB 11/24/98  Added Ada 95 applicability criteria.
