variable question

[wesf]

I'm new to Perl and have taken over a website built on the Interchange
framework. I have a problem that i tracked down to two variables $URL
$ and $EXPAND$. I know variables start with a $, but what's the
significance of the $ after the variable name?
Thanks,
Wes

As far as Perl is concerned: there is none. That trailing dollar sign does
not belong to the variable name.
Maybe it is some marker for the Interchange framework?

I suspect those are actually template placeholders; Interchange
(whatever that is) would substitute actual values as the page was
served.
