|Syntax||TURN [#ch,] degrees|
This command is part of the QL’s turtle graphics set and alters the current direction of the turtle in the specified window (default #1). When a window is first opened, the turtle will be facing the right hand side of the window (this is zero degrees).
TURN will force the turtle to turn anti-clockwise by the specified number of degrees (note that this does not work in radians!). If a negative number of degrees is specified, the turtle will be turned in a clockwise direction.
