Well, not really. It is true that 80-cells displays are awfully expensive. IMHO they are=20 also unwieldy due to their size: they are hardly portable, and they=20 require your hands to move twice as far which may sometimes impair=20 reading efficiency. So I never liked them. My braille display has 40 cells only. So even with a 80-cells limit I=20 always had to pan the display to see the whole line anyway. My text console is set to 160x128. The trick here is to have the number=20 of columns be a multiple of the braille display's width to avoid dead=20 areas when panning to the right. So if you ask me, I'm not against relaxing the 80 columns limit for=20 code. What really matters to me is that I can stay clear of any GUI. Nicolas --8323328-1427214125-1591369259=:1353413--
