RB>I know in DOS programming, I can do very fast textmode video reads and write

RB>pascal/2, i tried to put in the following code:

In OS/2, you're looking at Vio* calls, there is documentation of this in
an INF file called PRCP.INF (also contains docs on fullscreen Kbd* and
Mou* calls), you should be able to find it on the net as some sort of
ZIP file. Interrupts aren't used under OS/2, use Vio* calls instead.
You should find that your compiler can write lines very quickly using
Writeln(), character by character of course will be slower.
