Well, sorta. I woke up this morning, rethunk what I wrote, ran a test and
found, in fact, the % symbol *will* be PRINTed in your HTML without escaping
it. The other symbols, @ and $, OTOH, *do* need to be escaped. Hence:

Is still a mystery. Sorry 'bout that.

If you look at most Perl books that have sample code, you'll probably see a
readable "style", much more so than I've seen in a lot of random scripts
that I've pulled down from the web. You could also look at modules that may
already be on your server. I've found that many modules tend to be fairly
well organized, notated, indented, etc. Take a look at the "easier to read"
styles and apply the same formatting techniques to what you are working on
(if they are not applied already). *Then* start working.
Working with a poorly formatted script is just like dealing with FrontPage
code that someone dumps on you. When that happens to me, I almost always
take the time to "stylize" the code to the format I'm used to working in
(indents, notes, etc), which makes it easier for me to read...*then* I can
start working with it. Less confusing.
