CREATING A FILE UPLOAD FIELD

        ...

       When the form is processed, you can retrieve the entered
       filename by calling param().

              $filename = $query->param('uploaded_file');

       ...

       The filename returned is also a file handle.  You can read
       the contents of the file using standard Perl file reading
       calls:

               # Read a text file and print it out
               while (<$filename>) {
                  print;
               }

               # Copy a binary file to somewhere safe
               open (OUTFILE,">>/usr/local/web/users/feedback");
               while ($bytesread=read($filename,$buffer,1024)) {
                  print OUTFILE $buffer;
               }

        ...
