%RN

For the next screen I/O, this command suppresses Natural's automatic compression of screen data and causes the entire screen to be sent instead.

At a screen I/O, Natural usually does not send the entire screen, but only the changed screen data. When a non-Natural program is invoked which causes a screen I/O, Natural in most TP environments recognizes the non-Natural I/O and sends the entire screen upon the next screen I/O. However, in some TP environments, the non-Natural I/O is not recognized by Natural; in such a case, %RN should be used.

%RN only applies to the next screen I/O.
