+--
+-- OBJECTIVE
+--     Check pragma Reviewable.
+--     Check that pragma Reviewable is accepted as a configuration pragma.
+--
+-- TEST DESCRIPTION
+--     This test checks that pragma Reviewable is processed as a
+--     configuration pragma.  See CXH3001 for testing pragma Reviewable as
+--     other than a configuration pragma.
+--
+-- TEST FILES:
+--      The following files comprise this test:
+--
+--         CXH30030.A
+--      => CXH30031.AM
+--
+-- APPLICABILITY CRITERIA:
+--      This test is only applicable for a compiler attempting validation
+--      for the Safety and Security Annex.
+--
+-- SPECIAL REQUIREMENTS
+--      The implementation must process a configuration pragma which is not
+--      part of any Compilation Unit; the method employed is implementation
+--      defined.
+--
+--
+-- CHANGE HISTORY:
+--      26 OCT 95   SAIC   Initial version for 2.1
+--      07 JUN 96   SAIC   Revised by reviewer request
+--      03 NOV 96   SAIC   Documentation revision
+--
+--      03 NOV 96   Keith  Documentation revision
+--      27 AUG 99   RLB    Removed result dependence on uninitialized object.
+--      30 AUG 99   RLB    Repaired the above.
