PF> Yes.  Here is a mode 13 (320x200x8bit) sample.

 JP> info on these modes? I've never heard of
 JP> mode 13.

If you were using int 10 to set the video mode (which you never would under
OS/2),  you'd be asking for VGA mode 0x13.   Find a VGA tech ref for all of
the modes.

 JP> I got an error using /Oi120 :-

 JP> CIRC_FS.C(0:0) : warning EDC0463: Option /Oi20 is not valid.

 JP> This is using IBM C Set/2 v1.0.

I doubt very much my sample will work with that (awful) compiler.  You need
at least Cset++ 2.0.

 PF>      pchScreen = MAKEP(viopb.asel[0], 0);

 JP> What is MAKEP ?

  MAKEP(sel, off)

  The MAKEP macro combines a segment selector and an address offset to
  create a far (32-bit) pointer to a memory address.
