+--
+--     Under contracts F33600-87-D-0337, F33600-84-D-0280, MDA903-79-C-0687,
+--     F08630-91-C-0015, and DCA100-97-D-0025, the U.S. Government obtained

+--     PARTICULAR PURPOSE OF SAID MATERIAL.
+--*
+--
+-- OBJECTIVE:
+--      Check that the abortable part of an asynchronous select statement
+--      is not started if the triggering statement is a task entry call to
+--      a task that has already terminated.
+--
+--      Check that Tasking_Error is properly propagated to the asynchronous
+--      select statement and thus the sequence of statements of the triggering
+--      alternative is not executed after the abortable part is left. 
+--
+--      Check that Tasking_Error is re-raised immediately following the 
+--      asynchronous select.
+--
+-- TEST DESCRIPTION:
+--
+--      Use a small subset of the base Automated Teller Machine simulation
+--      which is shown in greater detail in other tests of this series.  
+--      Declare a main procedure containing an asynchronous select with a task
+--      entry call as triggering statement.  Ensure that the task is
+--      terminated before the entry call.  Use stripped down versions of
+--      the  called procedures to check the correct path in the test.
