Explanation of column contents
(0) Pointer to next contour element (to the row number of that column)
(1) Pointer to previous contour element
(2) Coding of contour mode for the movement
Possible values for X = abc
a = 10
b = 10
c = 10
(3), (4) Starting point of contour elements
(3) = abscissa, (4) = ordinate in current plane
(5), (6) Starting point of contour elements
(5) = abscissa, (6) = ordinate in current plane
(7) Max/min indicator: identifies local maximum and minimum
values on the contour
(8) Maximum value between contour element and abscissa (for longitudinal machining) or
ordinate (for transverse machining)
The angle depends on the type of machining programmed.
(9), (10) Center point coordinates of contour element, if it is a circle block.
(9) = abscissa, (10) = ordinate
