You are getting this error because you are treating an ordinary scalar $wfile like an indirect file handle. What are you trying to do with this? Why can't you just say 
$wfile = $cgi->param("toping");
open (my $dat,">", "/home/deruytja/webserver/rifucgi/temp_ul/$wfname")
+ or die 'Error processing file DAT: ',$!;
print $dat $wfile;

As a side note, there are a number of things you've done here which are poor practice from a modern web perspective, including 2 argument opens, bareword filehandles, and parroting unescaped text back to the browser. What resources are you using to learn Perl web scripting?
