Hopefully the title makes sense, but let's say I have a list "34 101 56 9 2 1289 0", how do I remove certain members based on indices?

I might have that list and a list of indices "2 5" so 101 and 2 would get removed...

Next time round the list might be a different length and there might be three indices to remove...

I'm struggling with things like zl.compare because the incoming list might contain duplicates, so it might be "121 34 5 87 5 34" and I can identify that indices "2" and "3" are "34" and "5", but I don't want to then remove all instances of "34"...

Basically, I want the "nthless" output from zl.nth, but for multiple indices.

Many thanks for any thoughts!

Well... long story short I have achieved this by filling a [coll] and removing items from there, but would still be interested to know if there's a better way of doing this to lists :)

zl nth insetad of coll, but otherwise i would also do it like this: copying only the ones you want to leave.

Here is the version without coll. The algorithm is quite simple, but there is a bunch of objects for bookkeeping and sanitizing input data.

here´s my approach, using zl exclusively.

the filter mechanism is a bit an abstract logic and could eventually made better in modern max versions.

for only one list element to be removed, you could f.e. use "prepend set" -> [route]

It is zero based, so one has to sub the filter list

I also prefer listfunnel version, but as filter length is now known,

from max 7 on, zl has indexmap mode.
