Hello,
I'm trying to translate a small Prolog programme into Pilog however I'm
stuck on some basic things. For example, how would you translate this
Prolog term:
intro :-
write("somme text ...").
which yields to (in Swi-Prolog):
?. intro.
somme text ...
true.
Best,
Er
Hi Alexander

Yes it helps a lot and thank you very much for taking the trouble to
clarify things.
Best Regards

Yes, but note that this talks about the symbol's *cell*, i.e. the
internal representation as described in doc64/structures.

"The CDR of a symbol cell is also called VAL, and the CAR points to the
symbol's tail. "
but val seems to equate to car from my tests so I'm confused
: (set 'x 3)
-> 3
: (car 'x)
-> 3
: (val 'x)
-> 3
: (cdr 'x)
!? (cdr 'x)
x -- List expected
Thank you very much Cristophe

My question came from that very documentation so I'm well aware of it.
I've never used a lambda but your Javascipt example helps a lot and
suggests that 'quote' in
((quote (X) (* X X)) 9)
transforms the statement into something like
(
(de anon (X)
(* X X)
)
anon 9
)
If that's r
