The output functions in Ada.Text_IO come in two forms:

procedure Put_Line (File : in File_Type; Item : in String);
procedure Put_Line (Item : in String);

The first form takes an explicit file to output to, the second goes to
Ada.Text_IO.Current_Output. 

Ada.Text_IO.Current_Output defaults to "standard output", but you can
set it to any other valid file.

So you have two options; you can write your code to use explicit
files, or you can set Ada.Text_IO.Current_Output at the beginning of
your program, possibly based on a command line argument.

If you use explicit files, you should consider passing the file name
as a command line argument.
