N50 M2
Explanation
In block N10, the starting conditions are assigned to the corresponding arithmetic parame-
ters. The calculation of the coordinates in X and Y and the processing takes place in N20.
In block N30, R1 is incremented by the clearance angle R3; R4 is decremented by 1.
If R4 > 0, N20 is reprocessed; otherwise, N50 with end of program.
