Thank you. I'll examine this code. As for the $1 vs \1, there were no warnings --- I'm only using perl from the command line in a bash script. I'm pretty much a complete perl noob. Thank you for helping.

    Perl noobs in particular should always enable warnings and strictures. One way to do this from the command line is
        perl -wMstrict -e "perl code here ..." whatever else ...
    (double-quotes for Windoze, single-quotes otherwise).
