Hi Bruce, extend stop 8 7
would mean, that if the algorithm reaches station 7 from station 8, it stops extending, turns back, and continues from some previous stations. If the algorithm will go the opposite way (11->7->8), extend stop 8 7 will be ignored. And to the general question: the b) is correct. Therion reads all extend statements, assign these options to oriented legs and stations, and then processes them. S.
