Hi,
I'm really new at the lisp and I need your help.
I have got a list When I call some function which looks like where S is the list and the N is a number.
This number(N) I want to add at the end of the list. The result should be
(5 6 4 2 N).
For example N=7 then the list is (5 6 4 2 7).
How can I do it ? Please help me.

Thanks in advance. Mike

One possible way to go about it would be to use reverse and push. Here's the descriptions of those:

It shouldn't be too hard to work out the details...

Another way is to use rplacd [ or (setf (cdr ...) ...)] on the last element of the list to destructively set it to (list N).

Another (non-destructive) solution: See http://www.lispworks.com/documentation/ ... append.htm
