I'm a little confused here. And I suspect you are too. What, exactly, are you trying to do?

Is this a CGI program that you want to run from a browser? In that case, it should write its output to STDOUT, not a file.

Or is this a command line program that is run to generate an HTML page which you will then upload to a web server? In that case, there is no need to print out a CGI header.

In either case, it's strange that you load the CGI.pm module and then completely ignore it.

I think that you don't really understand what you're trying to do. Please read a basic introduction to CGI programming.
