Suppose i have the following list:

'(a b c d)

What is a good way to replace one of the list-elements with another, so foe
example replacing the 'c with 'e?

But: i do not want using any c-functions, so i would prefer a solution without
using `substitute'!

Is the solution easier if i always want to replace the last element of the
list?

I think so, because it could be:

(defvar my-list '( a b c d))

(let ((temp-l (nreverse my-list)))
  (setcar temp-l 'e)
  (nreverse temp-l))

Is this a good elisp-solution? 

Thanks for help,
Klaus
