Universal Write-to-Operator
Universal Write-to-Operator
The Universal WTO (UWTO) utility is a command line utility for the z/OS UNIX System Services (USS) environment.
Universal WTO issues two types of messages to z/OS consoles:
- Write-To-Operator (WTO) messages
- Write-To-Operator-with-Reply (WTOR) messages
Universal WTO either:
- Writes a message to the z/OS console, and then ends (WTO).
- Writes a message to the z/OS console and waits for a requested reply (WTOR).
The type of message to be written (WTO or WTOR) is specified via the REPLY option. If WTOR is specified, the message is written to the console as a WTOR message and Universal WTO waits for a reply. The message reply is written to stdout.
