-- OBJECTIVE:
--     CHECK THAT A LOOP PARAMETER 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.
