Two important pieces of advice.
The first is to pick an
indentation style indenting between 2-4 spaces, and then
start using it. Now. Running your code through
perltidy will show
you what it looks like.
The second is to call functions with explicit parameters.
That means using parens. As documented in perlsub, if you
use just the plain & and in
a function you call another function, that other function
will get the parameters to the first as arguments.
Believe me. You may think these are picky details. But
they are not. The first strongly impacts how easy it is
to pick out your logic at a glance. The second is causing
a subtle set of side-effects that may or may not be
intended which a maintainance programmer may or may not
know enough to notice.

Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
