Here is another example of list processing related to "setpos"

I like this example of list processing, though I agree that it is advanced:

http://mia.openworldlearning.org/mwforum/msg02983.html

the "if.touching.many.do" procedure receives a list called "others".
It is a list of names of turtles.

"if.touching.many.do" processes that list by checking if each item in
that list touches the "main" turtle.

Here for example:

if.touching.many.do "pacman
[t1 t2 t3 t4 t5 t6 t7 t8 t9 t10 t11 t12 t13 t14 t15
 t16 t17 t18 t19 t20 t21 t22 t23 t24 t25]
[eatingpoints ask :touched [ht]]

the "others" list is:

[t1 t2 t3 t4 t5 t6 t7 t8 t9 t10 t11 t12 t13 t14 t15
 t16 t17 t18 t19 t20 t21 t22 t23 t24 t25]

and "if.touching.many.do" checks if "t1" and "pacman" are touching,
then if "t2" and "pacman" are touching, then if "t3" and "pacman" are
touching, then if "t4" and "pacman" are touching. etc.
