Using the CICS BROADCAST application
When you select Option 2 from the Operator Workstation menu, the CICS BROADCAST panel is displayed. Use this panel to send a one- to six-line message to CICS terminals connected to the CICS system named in the TGT field. Only VTAM terminals that are acquired and non-VTAM terminals marked as in-service will receive these messages.
The BROADCAST application requires that receiving terminals have full Basic Mapping Support (BMS) because the application uses the ROUTE command to send messages to terminals.
Routing messages using the panel does not interrupt the work at the terminal unless the terminal is involved in a pseudo-conversational transaction where the operator enters data on the panel but has not pressed ENTER prior to the routing of the message. In this case, the data would be lost. Depending on the work in progress or the state of an idle terminal, the message might not be received for a considerable time.

The CICS BROADCAST panel has three areas. The first area, the Control Area, is explained in the MainView AutoOPERATOR Basic Automation Guide, Volume 2.
In the middle area of the panel are six lines you can use to enter the text of the message you want to send. You can send the message lines to another CICS by changing the TGT field. By selecting a new target region and list of terminals, you can send the same message without re-entering the text.
The bottom area of the panel is a scrollable list of terminals on the target CICS system that are eligible for BROADCAST messages. Specific data about each terminal is displayed to help you select terminals to receive the message.
