also selection and cancellation), and if an axis movement outside the compensation plane is
programmed between these.

Points S1, S2, S3 and S4 belong logically to block N25. The machining sequence (visible in
the single block) is as follows:
..., N20, N25 (S1), N30 (retraction), N25 (S2), N25 (S3), N25 (S4), N35... This sequence is
also valid if N25 is a linear block.
