Either one will work, but to add more fuel to the fire, I can run the following code successfully:

#!perl.exe -w

use Strict;
use CGI;
my $q = new CGI;
print $q->header("text/html");

print"<h2>Turning Lights OFDF</H2>";

system "copy on.cgi on2.cgi"

Notice I turned the flag for Taint (-T) Checking off. This isn't the same command but executes without -T. I still can't seem to execute my system call for my X10 Module, but I think I'm starting to see the light.
