I thought I could pass the array to the sub and get back a hash right into another hash but obviously it's wrong.

Is this where I have to use reference to pass it back? 



sub sub1 {
   my %enc;
   for (@_) {
       chomp;
       if ( $_[0] =~ /^   "xxxx-(\d+):xxxxxx([^,]+),.+"$/ ) {
            $enc{$1} = $2;
       } else {
           next;
       }
   }
}


%hash1 = sub1(@dc);
