    FUNCTION

	full details.

    INPUTS

           number is ignored by this routine.
	String = pointer to the alert message string, as described above
	Height = minimum display lines required for your message
	Time = length of time the alert should wait for the user to
	    respond.  This time is the number of video frames the
	    alert should remain up for.

    RESULT
	A BOOL value of TRUE or FALSE.  If this is a DEADEND_ALERT, FALSE
	is always the return value.  If this is a RECOVERY_ALERT. The return
	value will be TRUE if the user presses the left mouse button in
	response to your message, and FALSE if the user presses the right hand
	button is response to your text, or if the alert could not
	be posted.  If the alert times out, the return value will be FALSE.
