Besides, the wrapping "\,(...)" is important, meaning "interpolate this Lisp expression's value here". For what you have in mind you could make use of the fact that `replace-regexp-in-string' also takes a function: (defun make-counter (startval) ; the "classical" counter closure (lambda (match) (prog1 (format "%d" startval) ; we have to evaluate to a string, I think (setq startval (1+ startval))))) (replace-regexp-in-string "ABC" (make-counter 23) "ABCM ABCI ABCJ ABCY ABC8= ") =3D> "23M 24I 25J 26Y 278" (don't forget lexical binding, it won't work otherwise ;-) Cheers - t --QRj9sO5tAVLaXnSD Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iEYEARECAAYFAmE/O2wACgkQBcgs9XrR2kaxawCfdsioIKeLMtugUCo+dgY86wAK DSAAn3cJAUp/Qql1gaQEcpMZTSmr/+Xv =uuVV -----END PGP SIGNATURE----- --QRj9sO5tAVLaXnSD--
