The indicated status specifies whether or not an
intersection exists (TRUE = intersection, FALSE = no
intersection).
Additional notes
Please note that variables must be defined before
they are used.
Programming example
Calculate the intersection of contour element 3 in
table KTAB1 and contour element 7 in table KTAB2.
The intersection coordinates in the active plane are
stored in CUTCUT (1st element = abscissa, 2nd
element = ordinate).
If no intersection exists, the program jumps to
NOCUT (no intersection found).
