Your question is ambiguous. Assuming you have a current buffer and a variable bound to a string, if you want to replace the line where the point is currently with the contents of your string, you could do: (delete-region (progn (beginning-of-line) (point)) (progn (end-of-line) (point))) (insert string) For example, to change the first line of the *scratch* buffer, you could evaluate: (let ((string ";; This is a new line for a lisp buffer.")) (with-current-buffer "*scratch*" (goto-line 1) (delete-region (progn (beginning-of-line) (point)) (progn (end-of-line) (point))) (insert string))) -- __Pascal Bourguignon__ http://www.informatimago.com/ “The factory of the future will have only two employees, a man and a dog.
