It seems that there is a typo in the examples given for DISPLAY MESSAGE. The description states:
DISPLAY MESSAGE ASYNC displays temporary message in the specified corner of the screen.
According to the syntax, this should be DISPLAY MESSAGE ASYNCH (i.e. with an ‘H’ at the end).
(I am not sure if there is a better method to report errors in the documentation. It may be useful to clarify in the documentation how to do that, or (even better) include a button/link in the documentation that directs you to the right place.)
