1 SUM
  Displays the terminal name (physical device name if terminal is a
  virtual terminal, remote node name and port name if terminal is a
  LAT device),  username,  and  process  identification code  (PID)
  of either specific  interactive users or all interactive users on
  the system.

  Format:


    SUM  [username]
2 Parameters

 username

  Specifies the user about whom you want information.  If you  specify
  a  string,  the  system  lists all interactive users whose usernames
  begin with the specified character  string.   For  example,  if  the
  string  MAR  is  specified  as a username, a list of all interactive
  users whose usernames begin with  MAR  is  displayed.   If  no  user
  exists  whose  username  matches  the  specified username string, an
  error message is displayed.

  If you omit this parameter, a  list  of  all  interactive  users  is
  displayed.
2 Command_Qualifiers

/FULL
  /FULL
  /NOFULL (default)

 Requests  that  the  full  physical device name of a terminal and the
 full remote node name of a terminal server be  displayed  instead  of
 the  default  which  is to display only the first eight characters of
 the physical device name and the first six characters of  the  remote
 node name.
/OUTPUT
 /OUTPUT[=file-spec]
 /NOOUTPUT

  Controls where the output of the command is sent.   If  you  do  not
  enter  the  qualifier,  or  if  you  enter  /OUTPUT  without  a file
  specification, the output is sent to  the  current  process  default
  output stream or device, identified by the logical name SYS$OUTPUT.
  If you enter /OUTPUT with a partial file specification (for example,
  specifying  only a directory), SUM  is the default file name and LIS
  the default file type.  If you enter a file  specification,  it  may
  not include any wildcard characters.

  If you enter /NOOUTPUT, output is suppressed.

  The  SUM command displays the process identification code (PID), the
  user name, process  name,  and  terminal  names  (both  virtual  and
  physical, plus remote node name and port name of LAT devices) of all
  interactive users currently on the system.  A user name  of  <login>
  indicates that someone is in the process of logging in.
