How do I add and delete a set of positions from two lists at the same time?

Since remove only removes one member at a time, then I could collect the lists that [remove] spits out and only keep the numbers in the list that appear more than once ... ? (This is a strange way of getting around the problem with [remove] though ...)

The easiest way is probably using the right outlet of [zl nth]

yes, zl nth works like remove. The problem is that it both [remove] and [zl nth] only deal with one number at a time. I would have to update the list every time I want to remove another number, and then I have not figured out how to avoid stack overflow ...

Hmm, and in the following code, it almost works, but there is still something wrong ...

Another set of zl objects, and without recursion, might make it easier to control.

eventually this is easier with [coll] compared to [zl] - but it might be
