OCS Window Traffic Handling

Each user operating one or two OCS windows is entitled (depending on their user ID profile) to nominate a system level procedure to help them filter and monitor messages sent to those windows.

These procedures are called MSGPROCs. The name of the procedure executed for a user to act as the MSGPROC for each user OCS window is defined as part of their user profile:

• A MSGPROC procedure has access to the serial stream of messages sent to the OCS window for which it is executing and can receive, modify, delete, or react to any message or message group sent to the window.
• MSGPROC procedures can therefore act as preprocessors for messages that an operator would otherwise have to monitor.
