Sending a General Information Message to a Specific User

Sometimes you need to send only a general information message to a specific user. For example, if you need to inform user VMUSER1 that the user is not authorized to use pack RC015, which the user just asked you to mount, enter the following command:
message vmuser1 you are not authorized to use pack rc015
As soon as there is no action pending at VMUSER1's display, the message appears on the display screen (provided the user is not running in full-screen mode or has not entered the SET MSG OFF command). Only VMUSER1 receives this message.
