Maybe there's a difference in the versions of perl on your two systems? For what it's worth, "Mixing reads and writes" in perlopentut says that you probably want: open (my $DATEFILE, "+<", $date_file) ... (and making that change to my copy of your script makes it work for me). -- Dan Scott Laurentian UniversityThread Previous | Thread Next
