in reply to win32/unix compatible code question

Internally, perl and Windows understand '/' as the separator just fine. If you are using external programs or libraries, all bets are off - some will handle it, some won't.

If you need to change the path separator based on underlying OS, File::Spec's catfile and catdir should help. It's a standard module, and its purpose is to "portably perform operations on file names".

An example:

#!perl use File::Spec::Functions; print catfile( qw/dir subdir file/ ); __END__ On my FreeBSD box, the result is "dir/subdir/file" On my Win2K box , the result is "dir\subdir\file"
