Departing blocks at deselection of TRC

Departing blocks are like approach blocks possible only for linear traverse blocks, i.e. during contour transitions: Straight line - straight line and circle - straight line. During the generation of departing blocks, two different departing strategies are possible. The standard type of departing blocks is shown in the following figure. The alternative departing strategy is selected with G138 (then G138 and G40 are present together in the same block). The alternative departing strategies are shown in the succeeding figure.
