ATM?

I try to write progs, which are portable between Linux and Windows. 
Under Linux the screensize isn't always the same.

I meant, it's much slower under Windows compared to Linux. 
But okay, you are right, that's not that important.

Okay, I also looked into some other source codes.
The most extreme is - of course - the DOS unit for Linux.
The suggestion was just meant as an additional aid.

Oh, I was surprised how easy it is to port console progs to Linux.

I don't think so. Except of the DOS unit and perhaps the Graph unit.
