HELLO

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.

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
