This is just a wild guess, but if you have a perl program named foo.pl and try to invoke it from the Windoze command line as
    >foo.pl
you will get a response from the OS something like the one you describe. Try the invocation
    >perl foo.pl
and see what happens.

See perlintro and perlrun.

Update: Added documentation links.
