subject: High Intensity Background Colours

LH> Does anyone know how to go about implementing high intensity background

The following program,  when run with any argmument,  will use the high
intense stuff.  This was written as an MSC 6.0 16bit OS/2 program.  It also
assumes your video card can handle "mode co80,34" (Which is most
of them).

     VioGetMode(&vi, 0);
     if(vi.row < 34){
         vi.cb = 8;
         vi.row = 34;
         VioSetMode(&vi, 0);
     }
 }

 {
     VIOINTENSITY vi;
     vi.cb = sizeof(vi);
     vi.type = 2;
     //VioGetState(&vi, 0);
     //vi.fs = !vi.fs;
     vi.fs = 1;
     VioSetState(&vi, 0);
