Sending a Warning Message to a Specific User

Sometimes you might have to send a high-priority message to a specific user. For example, user MVSOPR1 might submit a high-priority file that needs to be processed on printer 00E, but the printer is dedicated to user VMUSER1. Before you reassign the printer to user MVSOPR1, you might want to send user VMUSER1 the following warning message:
warning vmuser1 system needs printer 00e - draining in 5 minutes
If user VMUSER1 is not running in full-screen mode and has not entered the SET WNG OFF command, the user receives this message within the next 60 seconds and should stop sending files to this printer for processing.
