 Function       Changes the video page to be viewed on the CRT.
 Syntax         void qviewpage( char pagenum );
 Remarks        Standard TC routines are dedicated only to video page 0.
                However, most video cards, except MDA and some 3270 PC, have
                more than one video page.  This procedure enables you to
                view those pages.  The number of video pages available is
                detected by qinit and saved in maxpage.  pagenum is 0-based
                and the routine will only view other pages when pagenum <=
                maxpage.  The macro videopage is used to get/set the
                currently viewed page.
 Return value   None.
 Screens        All video pages.
 EOS            Unaltered.
