This should be simple for many of you.
I am trying to develop a function that searches a word definition stored in
a dict file.
As you can see, when reading a text, you might need to look for additional
information about the encountered word.
The following function searches the information for the word in the region.
(defvar sfl-dictionary-directory "~/Dropbox/ElmLab/dict")
(defvar sfl-base-dict-file "test5.txt")
(defun sfl-search-word-meaning ()
(interactive)
(let ((word
(buffer-substring (region-beginning) (region-end)))
(result))
(with-current-buffer
(find-file (concat sfl-dictionary-directory "/" sfl-base-dict-file))
(goto-char (point-min))
(search-forward word)
(set-marker (make-marker) (beginning-of-line))
(goto-char (end-of-line))
(setq result (buffer-substring (region-beginning) (region-end)))
(message result))))
But this gives an error
save-current-buffer: Wrong type argument: integer-or-marker-p, nil
It looks like (set-marker ... part is doing something wrong.
Could anyone point out the mistake I am making?

Look at "r" construct of C-h f interactive.

To take a `buffer-substring' you don't need a region or set markers.
Simply any two points will do. How about
(buffer-substring-no-properties (point-at-bol) (point-at-eol))
If you are searching, and have a successful match you can do for
example,
(buffer-substring-no-properties (match-beginning 0) (match-end 0))
I am not trying to solve your particular problem. I am just giving
hints for you to proceed ahead.

IMO this error is raised from inside `with-current-buffer'.
Seems it doesn't get the return value it expects, which looks like a bug for me,
as docstring doesn't mention a required return value, .
The result of last form "message" will be a string, which seems not being accepted.

Could anyone point out the mistake I am making?
Well, one mistake is posting HTML. I suppose that would be a "misgive",
actually. There are others... this means the primary mistake is to ask
for the (singular) mistake.
But enough negativity. A better question is: What can the programmer do
to explore this point in the behavior space, to find a path towards more
desirable behavior? One idea: do ‘M-x toggle-debug-on-error RET’ first.
