Thanks for the advice! The /usr/bin/perl on this AIX box is 5.8 so /r does not work, but I have 5.16 in an alternate directory, using it and adding /r to my first listing above works. I was not thinking modules because these are exercises for learning, but I guess the two are not mutually exclusive.
