 *              This routine is virtually the same as sAddrCmp, which is used
 *              to determine if two different addresses are the same. However,
 *              this routine can be used to determine if an address is the
 *              same as a previously stored address. The key difference is in
 *              the former case, if the address mode is "none", then the
 *              assumption is that the two addresses can not be the same. But
 *              in the latter case, the address mode itself is being compared.
 *              So two addresses can be identical even if the address mode is
 *              "none", as long as the address mode of both addresses being
 *              compared is the "none".
