in reply to printing to a file

Hi dudley.

I felt compelled to offer a little advice. In your open / close functions, I would include some minor modifications in the event of failure (hardware related, etc.).
open(FILE, $filein) or die "Couldn't open file $filein : $!\n"; close (FILE) or die "Couldn't close file : $!\n"; open (NEW, ">$filein") or die "Couldn't open $filein : $!\n"; close (NEW) or die "Couldn't close file: $!\n";

Even though perl will close filehandles for you, I feel it is unwise to not explicitly check for success / failure.

Hope this helps,
-Katie
