Enable or disable update toggle in full screen forms based commands
SET QUERYMODE ON | OFF | (<expL>)
If SET QUERYMODE OFF and SET UPDATE OFF are active then the [UPDATE MODE] key cannot be used to toggle into update mode. This prevents database updates from being performed through interactive forms based operations such as CHANGE, EDIT, and BROWSE. When QUERYMODE is OFF, the function keys that allow the user to position on other records through the CHANGE and EDIT forms are disabled. By default, QUERYMODE is ON.
