-- 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.

--         PWN 04/14/95  CORRECTED MINOR COPYRIGHT COMMENT PROBLEM.
