adding new member into a list( googled, tried to help myself already )

adding new member into a list( googled, tried to help myself already )

(OP)
Hi,
  I know the subject sounds really stupid, but I somehow met a problem that "the dumped number added into a list, but the list failed to be a list."
  This is a piece of short code. All I want to do in the dotimes loop is to "add the index which make deadOrAlive return true into the result list.":

  ( setq result '() )
  (dotimes ( x ( + 3 ( - ( car (last config) ) (car config) ) ) )
    ( setq index ( - (+ (car config) x) 1 ) )
    ( if ( deadOrAlive index config ) ( progn
                    ( append '( eval index ) result ) ) )


I dump the index which makes deadOrAlive return true, and those are number I want to add into the list, but it added ONLY FIRST index which makes deadOrAlive return true.

May someone tell me if there is any concept problem or any function I should use instead of append?
Thank you in advance.

RE: adding new member into a list( googled, tried to help myself already )

Try this (along with stylistic renamings):

CODE

(loop for index from (first config) upto (first (last config))
      when (alive-p index config)
      collect index)

Just so you know, '(eval index) produces a list of two symbols.  If you wanted index evaluated, it suffices to just have index.

Oh, yeah.  To push something onto a list, use PUSH:

CODE

(push index config)

You should use the Common Lisp Hyperspec instead of just google.  It has all sorts of useful information.
