/ADDRESS=ucb-address

    Indicates the device for which data structure information is
    to be displayed by the address of its unit control block (UCB).
    The /ADDRESS qualifier is an alternate method of supplying a
    device name to the SHOW DEVICE command. If both the device-name
    parameter and the /ADDRESS qualifier appear in a single SHOW
    DEVICE command, SDA responds only to the parameter or qualifier
    that appears first. /ADDRESS is functionally equivalent to /UCB.
