z/OS® Explorer allows sending messages to clients, similar to the TSO SEND command. Messages can be sent via an operator command (MODIFY SEND), a z/OS UNIX command (send) or the TSO SEND command. Messages are delivered immediately to connected users, and are also stored for users that log on later. This message buffer can be cleared using the operator command and the z/OS UNIX command.
