I do not know what a chart is. Maybe (setq mylist nil l1 '(a b c) l2 '(d e f)) (setq mylist `(,@l1 ,@l2 ,@l)) is what you want. Read about the "backquote construct" in the Emacs Lisp manual. Another function to explore in this context is =E2=80=98appen= d=E2=80=99: (setq mylist (append l1 l2 mylist)) > Here is my function, but need some form of loop, to traverse all the > function arguments. > > (defun linseq (&rest sequence) > sequence) > > (defun attach (chart &rest linsq) > (apply #'push linsq chart)) Again, I do not exactly understand what you want to acheive. =E2=80=98apply=E2=80=99 would not work in that example, because of its spec= ial handling of its last parameter. =E2=80=98funcall=E2=80=99 would. But neither is ne= cessary here. In principle, e.g., =E2=80=98mapc=E2=80=99 yields a way to loop over elemen= ts of a list (for side-effects only). But looping probably is not necessary, too. It is my strong impression, that you should take the time and work through a general introduction to (Emacs) Lisp first. A lack of that background just is too limiting.
