LOGON                                                  CP Privilege Class:  Any

Use the LOGON command to identify yourself to the VM/370 system and to access
that system.  The format of the LOGON command is:
+----------+------------------------------------------------------------------+
| Logon    | userid [password] [Mask] [Noipl]                                 |
| Login    |                                                                  |
+----------+------------------------------------------------------------------+
where:

userid   is the identifier assigned to you in the VM/370 system.

password is your password.  Specify this field if no protection (that is,
         masking characters) is desired.

Mask     types masking characters to cover your password on typewriter
         terminal without the print inhibit feature.

Noipl    specifies that the IPL device or name in the VM/370 directory should
         not be used for an automatic IPL.


Usage notes:

1.  If your terminal is already powered on when you want to use it, you can
    enhance security by turning power off and then on again, before using the
    LOGON command.  This ensures that the terminal is logically connected to
    your first level VM/370 system and not to some other user's virtual
    machine.

2.  Upon successful logon, VM/370 creates a virtual machine configuration from
    information in that user's directory entry.  The LOGON command name may not
    be entered using any line-editing symbols, but the operands may use these
    symbols.  See the VM/370 Terminal User's Guide for a detailed description
    of logon procedures.

3.  If you use LOGON because a teleprocessing line or terminal error
    disconnected you from your virtual machine, you have 15 minutes to log on
    again.  If you do not log on within 15 minutes, your virtual machine
    automatically logs off.  In this case, you may have to reconstruct files
    and restart jobs interrupted by the teleprocessing line or terminal error.

4.  If you previously issued the DISCONN command to run your virtual machine
    without a console and then issue the LOGON command to reconnect your
    console, certain SET and TERMINAL command operands are forced off even if
    they were on prior to issuing the DISCONN command.  For example, after a
    reconnect, CP resets the line delete character specified in the directory
    to the system default value.  Issue the QUERY SET and QUERY TERMINAL
    command lines to check which functions are currently active.

Resonses:

ENTER PASSWORD:
   indicates that the userid has been accepted.  You should now type in the
   password.

LOGMSG- hh:mm:ss mm/dd/yy
   indicates the time and date at which the system log message was generated or
   most recently revised.  All lines of the log message for which the first
   character is an asterisk are displayed at this point.  If you wish to see
   all of the system log messages, you must issue the CP command QUERY LOGMSG.

FILES: nnn ¦ NO  RDR, nnn ¦ NO PRT, nnn ¦ NO PUN
   This message is omitted if all counts are zero; otherwise, it indicates the
   number of spool files that exist for you at logon time.

LOGON AT hh:mm:ss zone weekday mm/dd/yy
   -- or --
RECONNECTED AT hh:mm:ss zone weekday mm/dd/yy
   indicates the time, day of the week, and date at which the LOGON or
   RECONNECT is complete.

GRAF raddr ¦ LINE raddr ¦ DEV resid  LOGON AS userid     USERS = nnn
   -- or --
GRAF raddr ¦ LINE raddr ¦ DEV resid  RECONNECT AS userid     USERS = nnn
   is the response to the primary system operator.  DEV resid specifies the
   resource identification of a 3704/3705 line.
