No magic needed, just MS-DOS 4.0. Then you can issue command "MODE ,50"
and you've got what you want - 50 lines under DOS. The reason for this
is that DOS screen handling functions before 4.0 were hardcoded for 25
line screen. So there is no way to make older versions to use 50 lines.
BTW, I'm using DOS 4.0, and I think it's much better than what most of
DOS 3.* users say. Oh, I almost forgot to mention, even under DOS 4.0
you need to have the ANSI driver installed.
