This is not so good. In fact, it's a little bit insane ;-)
You are creating a TFileStream in every iteration of the loop, none of
which are later freed. Also, there's a sleep(), which seems quite
strange. Try this instead:
S := TStringList.Create();
S.LoadFromFile(Filename);
for X := 0 to S.Count-1 do
writeln('Line ', X, ': ', S[X]);
S.Free();
