Description:
Ever wonder how to change the color of the border
around your screen in DOS text mode?  It's actually
very simple - just call DOS interrupt $10, function
$0B.  This sample code illustrates how.  You just drop
the BorderColor procedure into any of your DOS text
mode programs.

Program ChBorder;

procedure BorderColor(NewColor: byte); assembler;
{ simply call this procedure and pass it the number  }
{ of the color to which you would like the text-mode }
{ border to change. }
  asm
    mov ah, 0Bh
    mov bh, 00h
    mov bl, NewColor
    int 10h
  end;

begin
  BorderColor(2);
end.
