          202/19.  Replacement Commands

            201/Global search-and-replace operations are not needed as often in NMODE as
          they are in other editors, but they are available.  In addition to the simple
          Replace operation which is like that found in most editors, there is a Query
          Replace operation which asks you, for each occurrence of the pattern,
          whether to replace it.

            To replace every instance of FOO after point with BAR, you can do

          M-X Replace<CR>FOO<CR>BAR<CR>

          This invokes 203/replace-string-command201/.  Replacement occurs only after point,
          so if you want to cover the whole buffer you must go to the beginning first.
          Replacement continues to the end of the buffer.

          202/19.1  Query Replace

            201/If you want to change only some of the occurrences of FOO, not all, then
          you  cannot  use  an  ordinary  Replace.   Instead,  use  M-X  Query
          Replace<CR>FOO<CR>BAR<CR> (203/query-replace-command201/).  This displays each
          occurrence of FOO and waits for you to say whether to replace it with a
          BAR.  The things you can type when you are shown an occurrence of FOO
          are:

                  Space      to replace the FOO
                  Rubout     to skip to the next FOO without replacing this one.
                  Comma     to replace this FOO and display the result.  You are then
                              asked for another input character, except that since the
                              replacement has already been made, Rubout and Space are
                              equivalent.
                  Escape     to exit without doing any more replacements.
                  Period      to replace this FOO and then exit.
                  !           to replace all remaining FOO's without asking.
                  ^           to go back to the previous FOO (or, where it was), in
                              case you have made a mistake.

          If you type any other character, the Query Replace is exited, and the
          character executed as a command.

          202/19.2  Other Search-and-loop Functions

            201/Here are some other functions related to replacement.  Their arguments are
          strings.



                  M-X How Many<CR>FOO<CR> invoke 203/count-occurrences-command 201/and
                                  print the number of occurrences of FOO after point.
                  M-X Count Occurrences<CR>FOO<CR> Same as M-X How Many.

                  M-X            Keep            Lines<CR>FOO<CR>            invoke
                                  203/delete-non-matching-lines-command 201/and kill all lines
                                  after point that don't contain FOO.
                  M-X  Delete  Non-Matching  Lines<CR>FOO<CR>  Same  as  M-X Keep
                                  Lines.
                  M-X Flush Lines<CR>FOO<CR> invoke 203/delete-matching-lines-command
                                  201/and kill all lines after point that contain FOO.
                  M-X Delete Matching Lines<CR>FOO<CR> Same as M-X Flush Lines.
