Is there a cross reference to the next numbers by system code to the aliases they are tied to?

Hello,

I am looking for a cross reference to the next numbers and the aliases they update. For instance, in system 01 the first NN updates the AN8 but what does the other one update? Is there a cross reference for all of the aliases that get updated by system code?

Also, when using X0010 you have to know the index for the NN you are trying to get. Since the this BSFN uses an index for the NN array I would imagine there is a x-ref somewhere that ties this all together.

Thanks!
