Using a utl_file.file_type as a procedure argument

Question

Hi,
I'm trying to pass a utl_file.file_type variable defined in Proc A to ProcB as fllows:
Proc A:
output_file utl_file.file_type;
output_file := utl_file.fopen('E:\tmp\', 'traspas_merma.log', 'W');
call ProcB(output_file);
Proc B:
Procedure ProcB(filestr IN utl_file.file_type) IS
BEGIN
utl_file.put_line(filestr, str);
END;
When I compile I obtain the following error:
PLS-00363 Expression 'FILE' can be used as a destination assignment
So, whoy should I define the ProcB spec?
Thanks

Here is a code snippet that works:
declare
   procedure procb (filestr in utl_file.file_type)
   is
   begin
      utl_file.put_line (filestr, 'Some Text');
   end procb;
   procedure a
   as
      output_file   utl_file.file_type;
   begin
      output_file := utl_file.fopen ('TEMP', 'traspas_merma.log', 'W');
      procb (output_file);
   end a;
begin
   a ();
end;
