I am wondering how hard it will be to let gnu-emacs do the following: 1). Upon request, list all lines (and only these lines) which contain a certain string in the current buffer. For example, list those lines containing ``real*8'' in a FORTRAN program. 2). Edit these lines in the new buffer. For example, change some of the ``real*8'' to ``real*4''. 3). When the changes are done, exit the new buffer and return to the original one. Of course, the changes should not be lost. The reason I ask for this is that I have used an editor which has this feature. It was really nice because you can clearly see the changes you made to the file.

You can do this using `M-x occur', and another window will pop up containing all lines with the string you specified. >2). Edit these lines in the new buffer.

Steps 2 and 3 you can't do directly with off-the-shelf Emacs, but you can get something close with `M-%', which is query-replace. You might try getting help on both of these commands to see if together they do what you want.

Has nobody yet thought of commandeering Outline-Mode to do this? M-x outline-mode M-x set-variable outline-regexp ".*real\*8" M-x hide-body [edit to your heart's content] M-x show-all
