While working on this column, I discovered a bug in QuizQuestions.pm that stops reading the quiz file after the first line. Of course, this bug was difficult to track down, and when I finally found it, I was embarrassed to discover that it was the result of a misplaced curly brace. I'm sure that there are other bugs hiding in the software I print here and will try to correct things as necessary, here and/or at the Linux Journal FTP site, where the programs mentioned in this article are archived. QuizQuestions.pm is relevant enough to the rest of this article that I have included the corrected version in Listing 3.
Due to space considerations none of the three listings for this article are printed in this issue. Instead, they can be found on our web site (http://www.ssc.com/lj/) and can be downloaded via anonymous ftp in the file ftp://ftp.ssc.com/lj/listings/issue39/2319.tgz.
