[Closed] How to iterate through all sublayers of given layer?

I wrote a code that does something for each Editable Poly on given layer:

ilayer = layerManager.getLayer index
layerName = ilayer.name
layer = ILayerManager.getLayerObject index
				
nodes = refs.dependents layer
					
if(nodes == Undefined) do (
   messageBox "No objects on chosen layer." title: "Error"
   exit
)
for obj in (nodes as array) do (
    if(classof obj == Editable_Poly) do (
    ...
    )
)

I would like to also iterate through all sublayers of given layer. How can I do this?
