in reply to Why can't I open a file for writing?

Perhaps the bitwise or (|)? 

  open NEWFILE, '>', "$dir/subdirectory/$outputfile" | die "Can't open
+ $dir/subdirectory/$output
                                                here-^

      If you use || instead of or then you need parentheses for the open function: 

        open( NEWFILE, '>', "$dir/subdirectory/$outputfile" ) || die "Can't 
+open $dir/subdirectory/$output
