N110 X0 Y0 ;1. traverse statement defines starting
;values and 1st intermediate point:
;Master value: 0; Following value: 0

N200 CTABEND ;End of the definition; The curve table is
;generated in its internal representation
;as a polynomial up to the 3rd order;
;The calculation of the curve definition
;depends on the modally selected
;interpolation type
;(circular, linear, spline interpolation);
;The parts program state before the
;beginning of the definition is restored.
