Function
The blocks executed after CONTPRON describe the
contour to be prepared.
The blocks are not processed but are filed in the
contour table.
Each contour element corresponds to one row in the
two-dimensional array of the contour table.
The number of relief cuts is returned.
EXECUTE deactivates the contour preparation and
switches back to the normal execution mode.
Example:
N30 CONTPRON(...)
N40 G1 X... Z...
N50...
N100 EXECUTE(...)
