    Numerical control programs must be made at present in the mode MAN;
     see in addition Help / getting started  MAN.

     The numerical control words (RP, (STOP FED COOL INSERT.)) must be entered
     at present with the keyboard.

     With Alt-F "FROM", with Alt-W "WORK" is produced.
     Associated geometrical objects (points, outlines) can be selected.
     Conclusion with RETURN key or right mouse button.
     At each time one can re-establish each programstate with the cursor key up/down.

     You have to provide the partContour, starting points and workingContours
       with CAD or MAN.

    # Example:
    # start points:
    P20=P(100 100)
    P21=P(200 100)
    P22=P(50,50)
    P23=P(85 140 0)
    P24=P(120 140 0)
    P25=P(250 95 0)
    P26=P(260 100)
    P27=P(225 150)
    # partContour
    S20=REC P22 D(260 0 0) D(0 128 0)
    # workingContours
    S21=CCV  P23 P(92 140 0) P(95 150 0) P(100 150 0) P(103 140 0) P(110 140 0)
    S22=CCV  P24 P(140 140 0) P(130 160 0) P24
