Example: Overlapping pockets with islands
Inside machining with pilot drilling,
roughing-out and finishing.
PGM OVERL4 builds on OVERL3:
The main program section is expanded by the

finishing.
The contour subprograms 1 to 4 are identical to
the ones in PGM OVERL3 (see pages 8-27 and
8-28) and are to be added after block 39.
