TurnLeft                 Rotates the Turtle to the Left

 TurnLeft(Angle : Integer);                                           [TG/TP]

    Rotates the turtle's heading counterclockwise by the indicated number
    of degrees. Therefore a positive Angle turns the turtle to the left
    the indicated number of degrees, while a negative Angle turns the
    turtle to the right.

           Angle    Amount (in degrees) to rotate turtle.
