-- 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.
