LOGIN command

The LOGIN command begins your timesharing job and connects you to your
log-in directory.


     @LOGIN /FAST (USER) name (PASSWORD) password (ACCOUNT)account -
     (SESSION REMARK) remark


     name         is your user name.

     pwd          is your secret password (which  is  not  printed  on
                  your terminal)

     acc          is an account name or number that you are authorized
                  to use.

     remark       is an optional remark of up to  39  characters  that
                  identifies   the  terminal  session  for  accounting
                  purposes.   Check   with   INFORMATION   JOB-STATUS.
                  Change with SET SESSION-REMARK.

     /FAST        is an optional switch that prevents  the  following:
                  processing  of  your  LOGIN.CMD and COMAND.CMD files
                  and the system's  LOGIN.CMD  and  COMAND.CMD  files,
                  printing  of system mail, and printing of the notice
                  of new mail.  (Your system manager may  remove  this
                  switch from your system.)


     Acknowledgement of Valid Login

          The system acknowledges a valid LOGIN  command  by  printing
          your  job  number, terminal number, and the current date and
          time.  In addition, it prints the date and time of your last
          login.  You can use this information to determine if another
          user has learned your password and logged in to your account
          since the last time you logged out.

          Note that a batch job automatically logs in and logs out  of
          your  account.   The  batch  login sets the date and time of
          your last login and should  not  be  confused  with  illegal
          access to your account.

     Notice of User Mail and System Mail

          When you log in, the system notifies you if another user has
          sent  you  a  message  with one of the system mail programs.
          The  system  then  lists  any  system  mail  (mail  sent  by
          privileged  users  to  all users) that has accumulated since
          your last login.  Note that this mail  appears  in  the  log
          file if a batch job is run for you between the time the mail
          was sent and the time you logged in.

     Output from Command Files

          After a successful LOGIN, the system processes the LOGIN.CMD
          and  COMAND.CMD  files  in  the directory defined by logical
          name SYSTEM:  and the command files in your login directory.
          The files are processed in this order:

               1.  SYSTEM:LOGIN.CMD

               2.  LOGIN.CMD

               3.  SYSTEM:COMAND.CMD

               4.  COMAND.CMD

          The system displays any output from the  commands  in  these
          files  on  your  terminal.   After execution of each command
          file,   the   system   displays   the   message   "End    of
          file-name.CMD".   If the last command in the command file is
          a TAKE command  with  no  arguments,  this  message  is  not


     Getting the Attention of the System

          Before logging in, you may have to press any alphanumeric or
          special  character  to display the system herald or greeting
          and the @ prompt necessary for typing the LOGIN command.

          If you are dialing  in  by  telephone  to  a  line  declared
          autobaud  by  the  system  manager,  this  initial character
          enables  the  system  to  determine  your  terminal's  speed
          setting,  as  long  as  the  speed is 300, 1200, 1800, 2400,
          4800, or 9600.  Type a second character  if  the  terminal's
          speed  is 110 or 150.  If your initial character(s) fails to
          get the system identification message, press the  BREAK  key
          twice, followed by another character(s).

     Rights, Capabilities, and Charges

          The LOGIN command gives you ownership rights to your  log-in
          directory,  and  any group rights established for you on the
          public structure (usually named PS:).  In addition, you  are
          granted  whatever  capabilities  (for  example, Maintenance,
          Wheel)  have been awarded to you, and can be sure  that  any
          charges  you  incur for the use of system resources, such as
          CPU time or the batch and printing systems, will be recorded
          to your user name.


     Commands in Files Executed at Log-in Time

          For Affecting Entire Session or Current Level Only

               Commands that affect  your  entire  job,  for  example,
               TERMINAL  and  DEFINE,  belong  in LOGIN.CMD.  Commands
               that affect only the  current  level  of  TOPS-20,  for
               example, many SET commands, must be put into COMAND.CMD
               if you want them to  be  executed  automatically  after
               every PUSH command as well as after LOGIN.

          For Affecting Batch Jobs

               As soon as one of your batch jobs logs in,  the  system
               processes the command files in the directory defined by
               logical name SYSTEM:  and the  command  files  in  your
               login  directory.   The  files  are  processed  in this

                    1.  SYSTEM:BATCH.CMD

                    2.  BATCH.CMD

                    3.  SYSTEM:COMAND.CMD

                    4.  COMAND.CMD

               Note that certain parameters  of  the  batch  job,  for
               example,  its  time limit and the name of its log file,
               have  already  been  set  before  these  commands   are
               executed.   Such  parameters  are  set either to values
               specified by switches in the SUBMIT command that starts
               the  batch  job, or to default values in effect for the
               job issuing this SUBMIT command.  See also  Hints - For
               Affecting Nested Batch Jobs, below.

          Avoiding Duplicate Commands in Command Files

               After executing a SYSTEM:   command  file,  the  system
               executes  the  file  of  the  same  name  in your login
               directory.  The  SYSTEM:   command  files  may  contain
               commands  that  you  already  have  in your own command
               files.  To avoid executing  the  same  commands  twice,
               remove  duplicate commands from your command files.  To
               display a SYSTEM:  command file, give the command  TYPE

          For Affecting Nested Batch Jobs

               By  placing  a  SET  DEFAULT  SUBMIT  command  in  your
               BATCH.CMD  file,  you  cause  these  defaults  to be in
               effect for a nested batch job, (a batch job started  by
               a  SUBMIT command within the control file of another of
               your batch jobs).

          A Final TAKE Command

               To  suppress  the  display  of  the  message  "End   of
               file-name.CMD"  after execution of a command file, make
               the last command in the file a  TAKE  command  with  no

          Simplifying Log-ins

               By using the SET DIRECTORY ACCOUNT-DEFAULT command  you
               cause  subsequent  LOGIN  commands to require just your
               user name and password.

Special Cases

     Commands You Can Issue Before Log-in

          You can give these commands and arguments before logging in:

          Command                  Arguments

          SET                 LATE-CLEAR-TYPEAHEAD
          SYSTAT              (except with subcommands LPT or OUTPUT)

     Logging in to PTYs

          You do not need to give a password  when  logging  in  under
          your own user name to a PTY (pseudo-terminal).

     Must Log In Within Five Minutes

          If you do not log in within five  minutes  of  your  initial
          CTRL/C,  your  job  will be logged out automatically and you
          will have to type CTRL/C again.

     Logging in to Last Available Job Slot

          If you attempt to log in to the last available job slot, the
          system  will  not  log  you  in  but  will send you an error
          message instead.  This job slot is intended  for  users  who
          wish  to  attach detached jobs using the ATTACH command.  To
          log in a new job you must wait until  a  current  user  logs
