26 -- OBJECTIVE:
27 -- Check that the sequence of statements of the triggering alternative
28 -- of an asynchronous select statement is not executed if the triggering
29 -- statement is a protected entry call, and the entry is not accepted
30 -- before the abortable part completes. Check that execution continues
31 -- immediately following the asynchronous select.
32 --
33 -- TEST DESCRIPTION:
34 -- Declare a main procedure containing an asynchronous select with a
35 -- protected entry call as triggering statement. Declare a protected
36 -- procedure which sets the protected entry's barrier true. Ensure
37 -- that the entry call is never accepted by not calling the protected
38 -- procedure; the barrier remains false, and the entry call from
39 -- asynchronous select is queued. Since the abortable part will complete
40 -- before the entry is accepted, the sequence of statements of the
41 -- triggering alternative is never executed.
