How to create a list of lists in NetLogo?

Question

I want to create a list of lists in NetLogo. What I have is the following:

let a []
let b []
let c []
let d []
let l-o-l list [a b c d]

But then I get :

LIST expected 2 inputs on the right or any inputs when surrounded by parentheses.

with the list highlighted.

But when I change the last line to let l-o-l list (a b c d),
I have the b highlighted with Expected closing parenthesis.

I am confused!

Answer 1

Close! What you want is

(list a b c d)

When there is more than the normal number of inputs, it is the whole expression that is enclosed, including the list reporter.
