I've got this error message before,
because I must edit this sript directly on the unix machine.
If I edit on the windoze and transfer to unix,
I get this error message.
anyway this script works only from command line:
#!/usr/bin/perl -w

use strict;
use warnings;
use CGI;
my $query = new CGI;
use CGI::Carp qw(fatalsToBrowser);

$|=1;

In the browser I get:
"Internal Server Error"
It seems the whole HTML code must be inside of
