HELLO 

The HELLO command initiates an interactive session. 

Syntax 

HELLO [sessionname,]username[/userpass].acctname 

[/acctpass][,groupname[/grouppass]][;INPRI=inputpriority]
                                   [;HIPRI              ]
Parameters 

sessionname           Specifies an arbitrary name used in conjunction
                      with the username and acctname parameters to form a
                      fully qualified session identity.  The name must
                      contain from one to eight alphanumeric characters,
                      beginning with an alphabetic character.  The
                      default is no assigned session.

username              Specifies a user name that your system manager
                      assigns, enabling you to log on to this account.
                      The name must contain from one to eight
                      alphanumeric characters, beginning with an
                      alphabetic character.

userpass              Specifies a user password that your system manager
                      optionally assigns.  The password must contain from
                      one to eight alphanumeric characters, beginning
                      with an alphabetic character.  A slash (/) must
                      precede the user password.

acctname              Specifies the account name that your system manager
                      assigns.  The name must contain from one to eight
                      alphanumeric characters, beginning with an
                      alphabetic character.  A period (.)  must precede
                      the account name.

acctpass              Specifies the account password that your system
                      manager assigns.  The password must contain from
                      one to eight alphanumeric characters, beginning
                      with an alphabetic character.  A slash (/) must
                      precede the account password.

groupname             Specifies the group name that your system manager
                      assigns to be used for the local file domain and
                      the CPU-time and connect-time charges.  The name
                      must contain from one to eight alphanumeric
                      characters, beginning with an alphabetic character.
                      The default is your home group if your system
                      manager does not assign you a group name.  This
                      parameter is required if a home group is not
                      assigned.

grouppass             Specifies the group password that your system
                      manager assigns, but is not required to log on to
                      your home group.  The password must contain from
                      one to eight alphanumeric characters, beginning
                      with an alphabetic character.  A slash (/) must
                      precede the group password.

INPRI                 The value inputpriority determines the relative
                      input priority of the session used in checking
                      against access restrictions imposed by the
                      jobfence.  The value of this parameter becomes
                      effective at the time of logon.

                      The value of inputpriority can range from 1 (lowest
                      priority) to 13 (highest priority).  The default is
                      8.  If you supply a value less than or equal to the
                      current jobfence, access is denied to the session.

HIPRI                 Enables you to either override the system jobfence
                      or to override the session limit to log on.  If you
                      specify this parameter to override the jobfence,
                      the system first determines whether or not you have
                      system manager (SM) or system operator (OP)
                      capability.  If you have either of these
                      capabilities, you are logged on and your input
                      priority defaults to the system's jobfence and
                      execution limit.

                      If you do not have either capability and you
                      specify this parameter, the following message
                      appears:

                      MUST HAVE 'SM' OR 'OP' CAP. TO SPECIFY HIPRI,
                      MAXIMUM INPRI OF 13 IS USED (CIWARN 1460)

Operation Notes 

   *   Usage 

       You must enter this command from a terminal; you cannot use any
       other device to enter this command.  You cannot enter this command
       from a job, a program, or in break mode.  Pressing Break does not
       abort the execution of this command, but may prematurely terminate
       the printing of the welcome message.

       You must supply both a valid username and acctname in your logon
       command, or the system rejects your logon attempt and displays an
       error message.  If your logon attempt is accepted, the system
       displays specific logon information and prompts you for your next
       operating system command.  If your system administrator has set up
       a welcome message, it appears after the system verification of
       your logon.

       If you connect through a modem and do not log on within the
       allowable system-configured time, the line drops.  You must redial
       and press Return again.

       If you are already logged on and you enter the HELLO command, you
       are logged off your current session and logged on to a new
       session.

       In addition to the user and account names, you may be required to
       provide a group name and one or more passwords.

   *   Providing a group name 

       The group you select at logon for your local file domain is known
       as your logon group.  If your system administrator has associated
       a home group with your username, and if you want to use this group
       as your logon group, you need not specify it.  The system
       automatically assigns the home group as your logon group when you
       log on; however, if you want to use another group as your logon
       group, you must specify the name of that group in your logon
       string as shown in the following example:

            MPE XL:HELLO USER.TECH,MYGROUP 

       If your user name is not related to a home group, you must enter a
       group name in the HELLO command string, or your logon attempt
       fails.

   *   Entering passwords 

       Your system administrator can assign you user and group passwords
       to enhance the security of your account and to prevent
       unauthorized accumulation of charges against your account.  When
       you specify your home group as your logon group, you need not
       enter a password, even if your home group has a password; however,
       If you want to access any other account, user name, or group that
       has a password, you must supply the password when you log on.

       You can supply the password after the name of the protected
       entity, preceded by a forward slash (/).  For instance, if a group
       named XGROUP requires the password XPASS, and if you want to
       access this group as your logon group, you could enter the
       password as shown:

            MPE XL:HELLO USER.TECH,XGROUP/XPASS 

       For security purposes, the system also provides another method of
       entering passwords so that they do not appear to others in your
       work area.  To use this method, just enter the command string
       without the required password(s); the system will prompt you for
       the password(s).  The system turns off character echo so that what
       you type does not appear on the screen.  If you enter the
       incorrect password, the prompt reappears and you have two more
       opportunities to enter the correct password.  After the third
       incorrect entry, the message INCORRECT PASSWORD appears.  You must
       then press Return to receive a new prompt, and then you must enter
       the HELLO command again to start a new logon process.

   *   Access permissions and restrictions 

       After logging on, if the normal (default) file security provisions
       of the system are operative, you can access all files in your
       logon and home groups.  You can also read files and execute
       programs stored in the PUB (public) group of your account and the
       PUB (public) group of the SYS (system) account; however, you
       cannot access any other files.

Example 

To start a session with the following names assigned to the associated
parameters:

   *   ALPHA for the session name
   *   USER for the user name
   *   TECH for the account name
   *   XGROUP for the group name
   *   XPASS for the group password

Enter the following command string at the MPE/iX operating system prompt:

     MPE XL:HELLO ALPHA,USER.TECH,XGROUP/XPASS 

The system responds by displaying the following logon message:
