[Nagiosplug-help] Help with passing Nagios variables to custom plugin

Following advice from a user here, I used this code to dump the contents of the NAGIOS_* variables to a file when the perl plugin I wrote was called:

# Use this line below to dump the environment variables for debugging system "env|sort >/tmp/plugins_env.$$";

This seems to work correctly, and I end up with:
...

NAGIOS_HOSTADDRESS=10.253.192.204
NAGIOS_HOSTALIAS=www.jhuccp.org
...

which is exactly what I expected. Then I tried to use this value with: my %NAGIOS_ENV = map { $_ => $ENV{$_} } grep /^NAGIOS_/, keys %ENV;
...

   } elsif (defined($NAGIOS_ENV{NAGIOS_HOSTADDRESS})) {    $hostaddress = $NAGIOS_ENV{NAGIOS_HOSTADDRESS};
...

print DMP "hostaddress is $hostaddress.\n";

This outputs:
hostaddress is $HOSTADDRES$.

and the plugin fails.

Any suggestions on what I'm doing wrong or overlooking?

Thanks for you advice and suggestions.
