I thank you-all for your recommendations. After a single run, most of these Perl routines are destined for the dumpster; they are for my personal use in organizing a small cache of Bible studies. A few lines of Perl script which run in a few seconds, save me hours of typing. The studies, many of which are incomplete, I am editing and publishing, on the web (PDF and EPUB). I am working alone, so whatever does not get published before I die most likely shall never be seen.
