The CRT docs indicate that ScreenWidth and ScreenHeight are defined as 80 and 25 respectively. However, they seem to be undefined in the Win32 version of 1.9.2. I haven't checked any other versions.

Here's the example I tested:

program test;
uses
  Dos, Crt;
begin
  if CheckSnow then
    writeln('Wid: ',ScreenHeight);
end.

The CheckSnow call is there just to see if CheckSnow was defined.

Ideas?

Thanks.
