Writing and Deleting Messages (WTO, WTOR, and DOM Macros)

The WTO and WTOR macros allow you to write a message to a display device, a printer, a hard-copy log, or a program that receives WTO and WTOR messages (such as an EMCS console or a subsystem console). Besides writing a message, WTOR allows you to request a reply from the operator who receives the message. The DOM macro allows you to delete a message that is already written to the operator.
