Ok, some thigns I'd do is:
1) use strict; and use warnings; if winders has them.
2) Make you variabels my() variables; (IE my $arg1 ... Instead of $arg1 ...)
3) changeg system() line to :
system("C:\\perlcode\\validate.exe $arg $arg2") or die "System call failed $!";

Just curious, what is happening here with the >> and the &.
I see there's a 128 there, perhaps that's where it is coming from?

Since it's comign from a webserver do you have an
apropriate contetn type header before any output?
What do your logs say about it?
