Hi,

I am using the function that follows below to open files 
in a window where the filename is taken from lines like this:

  #: auth/pam.c:154 auth/sql.c:410 auth/sql.c:412

and then jump to the line number that follows the filename.  
so in this case it will open "pam.c" in a window and jump to
line 154. Its shortcoming is that it only opens the first  
file referenced. I would like it to be able to cycle through
all the references in a line like the one above in turn, with 
a message in between to the user like: "press enter for next 
reference, 'q' to quit".

I have looked at foreach but I am quite stuck so I could use
some help, not neccesarily a ready-made solution but some
pointers on how to do it.

   define view_source ()
   {
      variable str, file, n;
      narrow_to_whole_block ();
      recenter (1);
      if (0 == bol_fsearch ("#:"))
        { 
           widen_region ();
           error ("No source reference");
        }
      skip_chars ("#: \t");
      push_mark_eol ();
      str = bufsubstr ();
      n = strchop (str, ':', 0);
      file = strcat (dir + "/" + n[0]);
      if (0 == file_status (file))
        {
           widen_region ();
           verror ("Source file '%s' not found (use 'S' to set the path)", file);
        }
      popup_buffer (file);
      () = insert_file (file);
      set_buffer_modified_flag (0);
      most_mode ();
      goto_line (integer (n[1]));
      otherwindow ();
      fit_window ();
      otherwindow ();
      flush ("'q' closes source view");
      local_setkey ("close_buf", "q");
  }
