I have the following:

#!/usr/bin/perl -w
use strict;
use diagnostics;
use CGI qw(:standard);
use CGI::Carp qw(fatalsToBrowser);
print header(), start_html("Address Book for \u$ENV{USER}"), h1("Use A
+ddress Book");
[download]

What I want is the Title to read
"Address Book for Hoot"
but at the moment it is printing
"Address Book for - Netscape"

When I run the code from the command line it expands
$ENV{USER} and prints to the terminal:
"Address Book for Hoot"

Can someone tell me why it doesn't expand when called from the browser?

I am using RH9.0
