As an Ada.Sequential_IO file you can't. But you can achieve what I think
you want to using streams:
with Ada.Text_IO;
with Ada.Text_IO.Text_Streams;
procedure Example is
type Element is new Character;
use Ada.Text_IO;
begin
Element'Write (Text_Streams.Stream (Standard_Output), 'A');
end;
/*
It is perhaps an unfortunate feature of Ada that the standard i/o
channels are hardwired to the Text_IO file type.
