First I tested it with for example a buffer containing --- start of buffer 1 2 --- end of buffer so swapping 1 with 2 gives --- start of buffer 5816MHs 1 --- end of buffer string-temp was 5826MHs and with these 3 lines (goto-char (point-min)) (while (search-forward string-b nil t) ; string-b=2 (replace-match string-a)) ; string-a=1 string-temp is changed to 5816MHs and in the end, the last 3 lines do nothing. Any idea how to solve the problem? -- regards, Seweryn
