Yes, the Ford script does the same thing, but it's much more involved -- about 175 lines of code. Longer doesn't mean better, of course. I found your script and created the PL file. Much simpler, does the same thing, but uses a regular expression -- which Ford hasn't covered at that point in his book. There sure is a lot to learn here, and comparing the two scripts for "economy" and "verbosity" is just one of those things.
