Hi all,

I'm using a common Lisp compiler and I don't know the syntax to get the node "NIGHT" from the list (((GOOD))((NIGHT))). Could someone help me?

Thanks

Take it one step at a time with car and cdr:

define xs (((GOOD))((NIGHT)))

car xs --> ((GOOD))
cdr xs --> ((NIGHT))

car (car xs) --> (GOOD)
cdr (car xs) --> ()

etc.
