--     BUT ON THE INNERMOST ENCLOSING BLOCK, SUBPROGRAM BODY,

--     OR TASK BODY.

--     SUBTESTS ARE:

--       (A)  A SIMPLE TASK OBJECT, IN A VISIBLE PART, IN A BLOCK.

--       (B)  AN ARRAY OF TASK OBJECT, IN A PRIVATE PART, IN A FUNCTION.

--       (C)  AN ARRAY OF RECORD OF TASK OBJECT, IN A PACKAGE BODY,

--            IN A TASK BODY.

-- HISTORY:

--     JRK 10/13/81

--     SPS 11/21/82

--     DHH 09/07/88 REVISED HEADER, ADDED EXCEPTION HANDLERS ON OUTER

--                  BLOCKS, AND ADDED CASE TO INSURE THAT LEAVING A

--                  PACKAGE VIA AN EXCEPTION WOULD NOT ABORT TASKS.

--     PWN 01/31/95 REMOVED PRAGMA PRIORITY FOR ADA 9X.
