This read-write INTEGER specifies the index to use for read-next or read-block operations against the address table, and is initialized to -1 when the ELS-100 boots. An admin or script sets this to control where in the address table a subsequent read-next or read-block operation should begin, using the special -1 starting value to begin from the very beginning of the table. For example, to restart a full walk of the address table from scratch, an admin's script would set kxaddrIndex back to -1 before issuing the next read-next operation via kxaddrOperation.
