You may also want to look at the code in my state machine tutorial. It has two types of look up tables. One type is a table of variables that is in internal RAM for managing arrays of data. The other type is a table of code subroutine addresses that provide for a table lookup brach to a subroutine. The code attached to the State Machine Positing shows examples in assembly language of how to acccess both types of the tables.
