Determine whether fields displayed in forms should be underlined
SET UNDERLINE ON | OFF | (<expL>)
If SET UNDERLINE is ON, then fields in the full screen forms used in commands such as APPEND, CHANGE, EDIT, INSERT, QUERY and READ will be underlined on the screen. You would normally choose to either underline the fields, or highlight them in reverse video using the SET INTENSITY command. By default, UNDERLINE is OFF.
