Yeah, but read reads all the data at once, which I want to avoid. Files could 
be quite big.

nextN seems to jump over a lot of characters. not really lines as such, it 
seems.

Hmm... FileReader.new creates a var stream, which is a file.
The method next there gets the next line of data, so I guess I could use that 
to skip forward some lines, by just reading it and not doing anything with the 
data...
I could then keep a track of which line was at what file position, so I can 
more easily change the position in the file afterwards.

I think I could make it :)

I just wondered if someone else already did to save me some work :)

Marije
