2.9.2-8 Indicating 'Read-Only' Displays

When users are not authorized to change displayed data, "read-only" status should be indicated on the display.

Additional Information:
In applications where the use of read-only displays is common, some simple cue in the display header may suffice to indicate that status. In applications where users can usually make additions and/or corrections to displayed data, any exception to that practice may confuse a user and so should be noted more prominently on the display.
