-- OBJECTIVE:

--     CHECK THAT A DECLARATION IN A BLOCK STATEMENT HIDES AN OUTER

--     DECLARATION OF A HOMOGRAPH. ALSO CHECK THAT THE OUTER DECLARATION

--     IS DIRECTLY VISIBLE IN BOTH DECLARATIVE REGIONS BEFORE THE

--     DECLARATION OF THE INNER HOMOGRAPH AND THE OUTER DECLARATION IS

--     VISIBLE BY SELECTION AFTER THE INNER HOMOGRAPH DECLARATION.

-- HISTORY:

--     BCB 09/06/88  CREATED ORIGINAL TEST.
