Selects the reply portion of operand messages.When a message is received via Received Event, it will be set in WorkSpace 0. If we wish to analyze a received message, we can process it as-is. If we wish to respond to a received message, set Reply to true, and edit the reply portion. After this, when DefProc is called by the event handler function, messages requiring replies will send the reply message written in the reply section.
If we wish to send a message not from the Received Event handler but from the normal process, we create a message in Reply=false of WorkSpace 0.
