Displays the values of system parameters in the SYSGEN work area, plus
  the minimum, maximum, and default values of the parameters, and their
  units of measure.  Can also display the I/O driver database.

  Format:

    SHOW parameter-name
    SHOW /parameter-type
    SHOW /DEVICE=driver-name
    SHOW /HEX parameter-name
    SHOW /HEX/parameter-type

Additional information available:

parameter-nameQualifiers

  Name of a system parameter.  Use the SHOW /NAMES command to obtain the
  names of all the system parameters.

Additional information available:

/ACP/ADAPTER/ALL/BI/BUS/CLUSTER/CONFIGURATION
/DEVICE/DRIVER/DYNAMIC/GEN/HEX/JOB/LGI
/MAJOR/MULTIPROCESSING/NAMES/PQL/RMS/SCS
/SPECIAL/STARTUP/SYS/TTY/UNIBUS/XMI

 /ACP

  Displays the system parameters that affect the disk and magnetic tape
  ancillary control processes (ACP's).

 /ADAPTER

  Displays a list of adapters and what is connected to each nexus.

 /ALL

  Displays all the system parameters.

 /BI=BIindex

  Displays device addresses that are currently mapped in the I/O
  space for the VAXBI bus. It also displays node and nexus numbers
  and generic names of UNIBUS and MASSBUS adapters, VAXBI adapters,
  memory controllers, and interconnection devices such as the DR32
  and CI.

  Use of the SHOW/BI=BIindex command requires the CMEXEC privilege.

 /BUS=busId

  Displays the buses and any subsequent attached buses and all
  attached device node numbers, generic names of processors,
  memory modules, adapters, VAXBI adapters, memory controllers,
  and interconnection devices such as the NI.

  Use of the SHOW/BUS command requires the CMEXEC privilege.

 /CLUSTER

  Displays the parameters that are associated with a VAX cluster.

 /CONFIGURATION

  Shows devices by name, number of units, nexus number, adapter type,
  as well as CSR and vectors addresses. Requires CMEXEC privilege.

  Also accepts /ADAPTER = adapter-spec, /OUTPUT = file-spec, as well as
  /COMMAND_FILE, which formats all the devices as CONNECT commands to
  allow a complete re-configuration of a system's UNIBUS without the use of
  AUTOCONFIGURE.

 /DEVICE[=device-driver]

  Displays the device data base associated with a particular I/O device
  driver; if no device driver is specified, the database for all drivers
  is displayed. Requires CMEXEC privilege.

 /DRIVER[=device-driver]

  A short form of the /DEVICE display, only giving the beginning and
  ending addresses of the drivers.

 /DYNAMIC

  Displays the system parameters that can be modified in the active running
  system.  See WRITE ACTIVE for how to modify these parameters.

 /GEN

  Displays the structure-generating parameters and other parameters that
  take effect only at boot time.

 /HEX

  Displays the values in base 16.

 /JOB

  Displays the job controller parameters.

 /LGI

  Displays all login parameters.

 /MAJOR

  Displays the major parameters.  These are the parameters that are most
  likely to require adjustment for individual installations.

 /MULTIPROCESSING

  Displays  the  parameters  that  are  associated  with  symmetric
  multiprocessing (SMP).

 /NAMES

  Displays just the names of all the parameters.

 /PQL

  Displays the parameters that are used as the minimum and default for
  process creation limits and quotas.

 /RMS

  Displays the parameters that are used as the system-wide defaults for
  VMS RMS.

 /SCS

  Displays the parameters that are associated with the system communications
  services.

 /SPECIAL

  Displays all parameters that are reserved for DIGITAL use only.

 /STARTUP

  Displays the name of the current site-independent startup
  command procedure.

 /SYS

  Displays the parameters  that  are  associated  with  overall  system
  operation.

 /TTY

  Displays the parameters that are associated with the terminal driver.

 /UNIBUS

  Tests every word in UNIBUS I/O space and returns a list of addresses
  that respond and the value that was read. Note that this command is
  useful for debugging UNIBUS autoconfigure problems, but it is not
  recommended for use on a running system. All unibus adapters are the
  default, /ADAPTER=adapter-spec can be  specified.  Requires  CMKRNL
  privilege.

 /XMI=BIindex

  Displays device addresses that are currently mapped in the I/O
  space for the XMI bus. It also displays node and nexus numbers
  and generic names of processors, adapters, VAXBI adapters, memory
  controllers, and interconnection devices such as the NI.

  Use of the SHOW/XMI=BIindex command requires the CMEXEC privilege.
