beep2.1

beep

Emits a beep. Note that the beep sounds immediately, so several beep commands in close succession may produce only one audible sound.

Example:

beep                       ;; emits one beep
repeat 3 [ beep ]          ;; emits 3 beeps at once,
                           ;; so you only hear one sound
repeat 3 [ beep wait 0.1 ] ;; produces 3 beeps in succession,
                           ;; separated by 1/10th of a second

When running headless, this command has no effect.
