Does it show up in your env listing when you execute the system call?

For example.

#!/usr/bin/perl

use warnings;
use strict;

$ENV{'ANTH'} = "bignuts";
system('/bin/env');
[download]

when run like

# ./env.pl
[download]

will output, amongst other things:

ANTH=bignuts
[download]

If you do this (swapping the environment variable name and value as desired), does it show up when you execute this code?

cheers,
Anth
