How do arrays of arrays function?

[KatsAwful]

So OBSE does allow having an array of arrays, and I was hoping to use that for this scenario:

Its a randomized new start mod and for equipment randomization I have arrays of equipment and then an array of all those arrays. I want to get a random array from the array of arrays then do things on said array.

 

I'm not sure how I can get the array to work on from an array of arrays

If memory serves, you just add the (sub)array to the (main)array as you add any other element

(Disclaimer: I am not 100% sure ... has been some time.... just refreshed my memory from here)

Something like this (building the sub-array after)

let MyArray := ar_Construct array
Let MyArray[0] := ar_Construct array
Let MyArray[1] := ar_Construct array
Let MyArray[2] := ar_Construct array

Let MyArray[0][0] := <something>
Let MyArray[0][1] := <something else>
. . .

or like this (building the sub-array first)

let MyArrayA := ar_Construct array
Let MyArray[0] := <something>
Let MyArray[1] := <something else>

Let MyArrayMain := ar_Construct array
ar_append MyArrayMain MyArrayA

I managed to figure it out, thanks!
