WHEN TO ENTER A COMMAND OR SUBCOMMAND
The system lets you know when it is ready to accept a new command by
sending you the message:
READY
The ACCOUNT. EDIT, OPERATOR, OUTPUT and TEST commands have
subcommands. After entering one of these commands the system lets you
know it is ready to accept a subcommand by sending you the name of the
cQmmand. For example, in the following sequence you enter the OPERATOR
command after receiving a READY message. The system then sends you the
OPERATOR message indicating that you can enter any of the subcommands of
the OPERATOR command:
READY
operator
OPERATOR
If instead of entering a subcommand you want to enter a command,
enter the END subcommand to make the READY message appear again.
The system remains able to receive commands until you enter one of
the five commands that have subcommands. The system then accepts only
that command's subcommands until you request a READY message by entering
the END subcommand.
HOW TO ENTER A COMMAND OR SUBCOMMAND
After you receive a message letting you know the system is ready to
receive a command or subcommand, do the following:
1. Type the command or subcommand name and the selected operands.
2. Correct any typing mistakes with the character-deletion and
line-deletion characters.
3. Press the RETURN key.
If all the operands do not fit in one line you should follow this
sequence:
1. Type the command and subcommand name and the selected operands.
2. Type a hyphen (-) at the end of the line.
3. Press the RETURN key.
4. Continue entering the operands. If they do not fit in the second
line repeat from
2,.
5. Press the RETURN key to enter the command.
You can type command and subcommand names and operands in either
uppercase· or lowercase letters. You may prefer to type your commands
and subcommands in lowercase since it is usually more convenient, and it
allows you to distinguish your input from the system's messages in your
listing. (The system prints in uppercase letters.) All examples in
this manual show the user's input in lowercase letters, and the system
output in uppercase letters.
