-- OBJECTIVE:
--   CHECK THAT A SUBTYPE CAN BE NONSTATIC IN A GENERIC TEMPLATE
--   AND STATIC IN THE CORRESPONDING INSTANCE.

--   CHECK THAT IF A GENERIC PARAMETER IS A STATIC EXPRESSION AND THE
--   CORRESPONDING (IN) PARAMETER HAS A STATIC SUBTYPE IN THE INSTANCE,
--   THEN EACH USE OF THE FORMAL PARAMETERS IN THE INSTANCE IS SAID TO
--   BE STATIC.
--
--   A NAME DENOTING A CONSTANT DECLARED IN A GENERIC INSTANCE IS
--   ALLOWED AS A PRIMARY IN A STATIC EXPRESSION IF THE CONSTANT
--   IS DECLARED BY A CONSTANT DECLARATION WITH A STATIC SUBTYPE
--   AND INITIALIZED WITH A STATIC EXPRESSION.
--
--   THIS IS A TEST BASED ON AI-00505/03-BI-WA.

-- HISTORY:
--         EDWARD V. BERARD, 27 AUGUST 1990
--         DAS   8 OCT 90   ADDED CODE TO MATCH EXAMPLE 1 IN
--                          AI-00505.
--         JRL 05/29/92  CORRECTED MINOR PROBLEM IN REPORT.TEST STRING.
--         JRL 02/18/93  EXPANDED TEXT OF REPORT.TEST STRING.
