SetHeading               Sets Heading for Turtle

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

    Sets the turtle's heading to a specific angle. The possible range is
    0..359, where 0 (North) is up, 90 (East) is right, 180 (South) is
    down, and 270 (West) is left.

           Angle    New heading for turtle; range is 0..359.

           Note:    Angles not in the range 0..359 are modified. Negative
                    angles go in a counterclockwise direction; that is,
                    the actual angle is (360 + Angle). For example, if the
                    Angle is -3, the actual angle is 357. An Angle that is
                    larger than 359 is modified so that the value 'Angle
                    MOD 360' is used instead.
