LOGGING

OPERATOR CONSOLE MESSAGES

Whenever a user gives a HELLO or BYE Command at a terminal, the System
Operator Console will print a message recording the event.  The format is
as follows:

LOGON, LOGOFF

                 **LOGON IDcode time terminal #
                    or
                 **LOGOFF IDcode time terminal #

where

    IDcode is the users IDcode.

    time is the time (on a 24-hour clock) system.

    terminal # is a decimal number from 0 to 15 identifying the
               terminal.


Examples:

                 **LOGON   A000  0905  #05
                 **LOGOFF  A000  0905  #05

The printing of the LOGON and LOGOFF messages will interrupt any printing
currently being done on the System Operator Console.  If the mode switch
is set to "KT" or "T", the message will be punched as well as printed.



EXAMPLE:

    DIRECTORY
          ID   NAME    DATE    DISC ADR  LENGTH
         A000  BARREL  069/69  0/14/032  0383
               CAR     069/69  0/14/026  0383
               FIG     066/69  0/14/000  0128
    **LOGOFF  A000  0905  #05
               GETH    069/69  0/14/014  0383
               H123    069/69  0/14/008  0383
               VANPO   069/69  0/14/002  0383
               YTELL   069/69  0/14/020  0383

A user may logon with a HELLO Command when the previous user has not
logged off with a BYTE Command.  In this ase the system will automatically
log off the previous user before logging on the current user.

Figure 6-1 represents the sequence of events occurring when users log on
and off two user terminals.  Note that user-A000 logs on to terminal #14
while user-H909 has not logged off.

                                                  READY





HELLO LIBRARY PROGRAM

When the user logs on with a HELLO Command, the system will search through
the system library to see if a program exists with the name HELLO.  If one
does exist, this program will be executed.  User-A000 can use the HELLO
program to pass information about the system to other users.  The HELLO pro-
gram runs only once and it is removed from the user area when it terminates.
If no HELLO program exists, the message READY will be printed on the user
terminal.  After a BYE Command the system prints on the user terminal the
time used in this access.
