Subject: Re: Console width?

I don't know what your application is. In all cases when I needed to 
modify the last line of output, I would send a line feed (\r) and 
rewrite completely. It seems to always be simpler than doing tricky 
calculation on how many character to go back.

Something like:

$stdout.sync = true
10.times { |i| print("\ri=%2d!!!" % i); sleep(1); }
puts

For anything more complicated, curses should be it, although I have no 
experience in this area.
