These values are at least four digits after being shifted to the left and encoded with other data. In order to form the Absolute Memory Address for each value we need, we need to shift 4 to the right and add the KiServiceTable address. We want to do this at each entry point of the table and output the symbols associated with the absolute address. To achieve this, we can
