You must be at the wrong website. This site is about the
language Perl (which doesn't have "null"s nor "NULL"s).
Pearl can be found at
http://people.ku.edu/~nkinners/LangList/Langs/P/PEARL[1].htm,
http://people.ku.edu/~nkinners/LangList/Langs/P/PEARL[2].htm,
http://people.ku.edu/~nkinners/LangList/Langs/P/PEARL[3].htm,
and
http://people.ku.edu/~nkinners/LangList/Langs/P/PEARL[4].htm
(4 different languages).
(I'd normally make them links, but [ ] doesn't
seem to like nested brackets, and I can't get perlmonks
to recognize
<a href = "foo">bah</a> as an HTML element.)
