You're wrong, on Windows/DOS, Perl thinks of "\n" as chr(10), too. It's only that when reading from a text file, thus with binmode disgarded, the contents read from the file is modified so a chr(10) (="\n") is substituted for every chr(13).chr(10) pair in the file.

On printout to a text file handle, the reverse happens: Every chr(10) is replaced by chr(13).chr(10).

The net effect, and the whole point of this elaborate exercise, is that on these platforms, "\n" is a single character too.
