Execute The Contour Elements Of A Table Block-By-Block (Exectab) - Siemens SINUMERIK 840D sl Programming Manual

Example
Calculate the intersection of contour element 3 in table TABNAME1 and contour element 7 in
table TABNAME2. The intersection coordinates in the active plane are stored in the variables
ISCOORD (1st element = abscissa, 2nd element = ordinate). If no intersection exists, the
program jumps to NOCUT (no intersection found).
Program code
DEF REAL TABNAME1[12,11]
DEF REAL TABNAME2[10,11]
DEF REAL ISCOORD [2]
DEF BOOL ISPOINT
DEF INT MODE
...
MODE=1
N10 ISPOINT=INTERSEC(TABNAME1[3],TABNAME2[7],ISCOORD,MODE)
N20 IF ISPOINT==FALSE GOTOF NOCUT
