in reply to Environment Variables

You can do a 
print "Content-Type: text/html\n\n";
foreach (keys %ENV) { print "$ENV{$_} <BR>\n"; }

[download]
and see what's available to you.

update: obviously that was really silly of me to leave off the key in the printed value.. sheesh.. workin in windows makes me stupid. Thanks for correcting that maverick.

    Would also be helpful to see what key has what value :) 
    print "Content-Type: text/html\n\n";
foreach (keys %ENV) { print "$_ => $ENV{$_} <BR>\n"; }

    'course Data::Dumper is your friend.... 
    use Data::Dumper;
print "Content-Type: text/plain\n\n";
print Dumper \%ENV;

    [download]

    /\/\averick
    perl -l -e "eval pack('h*','072796e6470272f2c5f2c5166756279636b672');"

[d/l]
[select]

      Of course you should remember to remove Data::Dumper afterwards... I'm told it is quite heavy on the processing

      Although I confess I've never used it :)

      Sorry, Apparently its not heavy on processing, just worth removing because of its actual size!!! (1000 lines)
