Your original problem was with
for Ind in 1..Length(CHAINE) loop
begin
if IS_BASIC(ELEMENT(CHAINE,IND)) then
EMPILER(LA_PILE,ELEMENT(CHAINE,IND));
else DELETE(CHAINE, IND,IND);
end if;
end;
end loop;
So suppose Length(CHAINE) started at 10; we're looping from 1 .. 10.
Now suppose you execute the DELETE. That means that now Length(CHAINE)
is 9, *but* you are still looping from 1 .. 10; so that when IND gets to
10 (the loop range doesn't alter), ELEMENT(CHAINE,IND) is trying to
access an element which doesn't exist.
