[newbie] problem reading a file

Hi Stephan,
Fo some reason the version of fromFile that takes a File, not a String, is being used. See http://www.scala-lang.org/docu/files/api/scala/io/Source$object.html#fromFile%28java.io.File%29 versus http://www.scala-lang.org/docu/files/api/scala/io/Source$object.html#fromFile%28String%29/. I'm afraid I can't tell you off the top of my head why this is.

Thanks for any advice and best regards, Stephan.

In 2.8, use fromPath if you pass a String, and fromFile if you pass a java.io.File.

Thanks, Rex. I was reading the 2.7 api doc. Now I found
the 2.8 api doc which told me that toLine needs also a
line separator string; thinks work out so far.
