In your code: #!c:/perl/bin/perl -wt
In addition to what everyone else said, -t doesn't seem to be a valid switch; you need -T for taint mode. (-t gives an error even on Windows.)

(Update: Sorry, the -t switch produces an error in perl v5.6.1, but not in v5.8.0. My mistake...unless the original poster is using a version where -t isn't recognized...)
