NoWrap                   Disables Automatic Turtle Wraparound

 NoWrap;                                                              [TG/TP]

    Disables automatic wraparound of the turtle. If the turtle moves out
    of the current window, it disappears and remains invisible (and unable
    to draw) until it moves back into the current window.

           Note:    NoWrap is the default initial state.
