OK, I think I solved my problem: replace-regexp "!.*" " " and all the comments are gone, and the line numbers are unchanged. Now, the resulting file can be saved under a different file name, or the buffer could be renamed and the intended regexp search can be performed, either with occur or isearch-regexp. Thanks all anyway. Best, FCC. PS. If there is a better solution, I would like to hear it.
