-- OBJECTIVE:

--     CHECK THAT A DECLARATION IN A DECLARATIVE REGION OF A TASK

--     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 08/29/88  CREATED ORIGINAL TEST.
