like this? (haven't tested it because temp. out of acces to AutoCad so just pasted something together in notepad) ; independent simple dialog for getstring so no switching needed from dialog to command line (_ask "How are you?") (defun _ask ( $m / f p d r s) (if (and (setq f (vl-filename-mktemp ".dcl"))(setq p (open f "w"))) (progn (write-line (strcat "ask :dialog {label =\"" $m "\";:edit_box {key=\"eb\";}spacer;ok_cancel;}") p)(close p)(gc) (setq d (load_dialog f))(new_dialog "ask" d) (mapcar '(lambda(x y)(action_tile x y)) '("eb" "accept" "cancel") '("(chk_val $value)""(done_dialog 1)""(done_dialog 0)"))(setq r (start_dialog))(unload_dialog d)(vl-file-delete f))) (if (and (= r 1) (= 'STR (type s)) (/= s "")) s nil) ) (defun chk_val (v) (if (and (not (null v))(eq (type v) 'STR)(not (eq v ""))) ;;; if part of larger dialog write back to edit box ;;; (set_tile "eb" (setq s (strcat (vl-string-trim "\"" v) "\""))) ;;; else just return value (setq s (strcat (vl-string-trim "\"" v) "\"")) ) ) (defun c:t1 ( / r ) (if (setq r (_ask "how many inches ?"))(alert (strcat "result = " r))) (princ) )

Worked really fine. My intention is click under a line like Kerbline and change me to Kerbline_LVL and start to create a Point Levels. The lisp routine to create point levels is working fine, but I was stalling on the part of switching to the previous layer. Thank you very much Steven!!

Just come across this old post, it is possible if you pick Alignment property insertion and right-click on it or in the other words, hit the alignment property definition line to all grips appear and roll over it (don't select)just right click on the middle square.
