An informational message tells you about the status of the system or of your terminal session. You do not need to respond to an informational message.

Informational messages include a message identifier (message ID) and are documented in z/OS TSO/E Messages. If messages at your terminal do not display a message ID, you can change your profile with the PROFILE MSGID command to display message IDs. For more information about the PROFILE command, see Changing Your User Profile with the PROFILE Command.

Like prompting messages, informational messages may have two or more levels. If an informational message ends with a plus sign (+), you can request an additional message by entering a question mark (?) in the leftmost space under the message as described previously in Prompting Messages.
