                 VOPENTERM. If not already set, the following comarea 
                 items must be set before calling VTURNOFF.

Discussion 

VTURNOFF is used for momentarily switching from VPLUS/V block mode to
character mode.  This procedure is designed for use after a terminal has
been previously opened by VOPENTERM or after a VTURNON.

VTURNOFF reconfigures the terminal and driver for character mode
operations without disturbing the screen image on the terminal.  The
following operations normally performed in VCLOSETERM are not performed
in VTURNOFF:

 *  Clear local form storage

 *  Enable the USER/SYSTEM keys

 *  Disable touch reporting, delete touch fields

 *  Clear screen

 *  Unlock keyboard

 *  Close terminal file
