-- "+" AND "-" FOR PREDEFINED LONG_INTEGER WHEN THE RESULT IS
-- OUTSIDE THE RANGE OF THE BASE TYPE.
-- APPLICABILITY CRITERIA:
-- THIS TEST IS APPLICABLE IF THE IMPLEMENTATION HAS A

-- IF LONG_INTEGER IS NOT SUPPORTED, THEN THE DECLARATION OF
-- "TEST_VAR" 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:
-- TBN 10/07/86 CREATED ORIGINAL TEST.
-- JET 12/30/87 ADDED CODE TO PREVENT OPTIMIZATION.
-- JRL 03/30/93 REMOVED NUMERIC_ERROR FROM TEST.
