Dominic,
I would find it much easier to try to help you if you would put your
comments _after_ the part of my message that you are responding to. As
I have done in this article.
Indeed, I had to read to the end before I found out it was my article
you were replying to. So you nearly didn't get a reply at all (of
course, you may not care!)

I understood that ..

This is your code (slightly reformatted):
procedure si_fic_existe (fichier : out ada.text_io.file_type;
mod_fic_ecr : in ada.text_io.file_mode;
nom_fic : in string) is
begin
ada.text_io.open (fichier,mod_fic_lec,nom_fic);
ada.text_io.close (fichier);
raise sortir_program_principal;
exception
when ada.text_io.name_error => null;
end si_fic_existe;
and I'm suggesting that this would be even more useful:
procedure si_fic_existe (nom_fic : in String;
mod_fic_ecr : in ada.text_io.file_mode) is
fichier : ada.text_io.file_type;
begin
ada.text_io.open (fichier, mod_fic_lec, nom_fic);
ada.text_io.close (fichier);
raise sortir_program_principal;
exception
when ada.text_io.name_error => null;
end si_fic_existe;
because you aren't asking your caller to supply a variable (fichier)
which is of no use to him after your procedure has returned.
