CN Operand

You can use the CN operand to send messages to a specific operator console. The console may be a system console or an extended MCS console.

A system console is known to the system by a console identifier or a console name defined by your installation. To send a message to a specific system console, use the CN operand with the console identifier or console name enclosed in parentheses.

An extended MCS console is not associated with a physical device. For example, a user with a TSO/E CONSOLE command authority can act as an extended MCS console. An extended MCS console is known to the system by a console name (usually the user's user ID). To send a message to a specific extended MCS console, use the CN operand with the console name enclosed in parentheses.

The console name that you specify with the CN operand must be 2 to 8 characters and must begin with an alphabetic character or one of the special characters #, $, or @. The remaining characters may be alphanumeric.

The console identifier that you specify with the CN operand (for system consoles only) must be from 0 to 99. If you specify CN(0), the system sends the message to the master console operator.

Example
To send the following message to the operator console identified by the number 29, enter: `SEND 'Did you mount the tapes?' CN(29)`

Example
To send the following message to the operator console identified by the name TAPE1, enter: `SEND 'Please load tape AFD045.' CN(TAPE1)`
