         SHOW DEVICE [name] [/ADDRESS=n]

     Displays the I/O data structures associated with a device.
     The device name can be a generic name (DB for example), which shows
     all I/O structures associated with that device type; it can be a
     specific name (DBA1 for example), which shows all I/O structures
     associated with that particular device; or it can be omitted, which
     shows all the I/O structures for all devices in the system.
