Here's an iterative version to compare to your recursive implementation: (defvar enlarge-window-char ?_) ; or ?+ (defvar shrink-window-char ?-) (defun resize-window (&optional arg) "Interactively resize the selected window. Repeatedly prompt whether to enlarge or shrink the window until the response is neither `enlarge-window-char' or `shrink-window-char'. When called with a prefix arg, resize the window by ARG lines." (interactive "p") (let ((prompt (format "Enlarge/Shrink window (%c/%c)? " enlarge-window-char shrink-window-char)) response) (while (progn (setq response (read-event prompt)) (cond ((equal response enlarge-window-char) (enlarge-window arg) t) ((equal response shrink-window-char) (enlarge-window (- arg)) t) (t nil))) ;; no loop body needed ) (push response unread-command-events))) -- Kevin Rodgers Denver, Colorado, USA
