-- APPLICABILITY CRITERIA:
--      THIS TEST IS APPLICABLE ONLY TO IMPLEMENTATIONS THAT SUPPORT
--      THE PREDEFINED TYPE "LONG_INTEGER".

--      IF SUCH A TYPE IS NOT SUPPORTED THEN THE DECLARATION OF THE
--      VARIABLE "F" MUST BE REJECTED.

-- *** NOTE: This test has been modified since ACVC version 1.11 to    -- 9X
-- ***       remove incompatibilities associated with the transition   -- 9X
-- ***       to Ada 9X.                                                -- 9X

-- HISTORY:
--      RJW 09/01/86  CREATED ORIGINAL TEST.
--      JET 12/30/87  UPDATED HEADER FORMAT AND DEFEATED OPTIMIZATION.
--      JRL 03/30/93  REMOVED NUMERIC_ERROR FROM TEST.
