Hi everyone.

I use SWI-Prolog version 5.6.27.

Here is my code :
go :-
write('y or n : '),
read(X),

% Here I get what I wrote
writeln(X),
X == y, writeln(yes);

% Here, the value is lost
writeln(X), writeln(no).

Why do I obtain this ?

Because of ; I think.
You could try using if-then-else construction.

Best regards
