Hi emacsers
Below is quite strange to me.
(setq file-name "test")
(describe-variable 'file-name)
,----------- output
| "file-name's value is nil
|
| Documentation:
| Not documented as a variable."
`-----------
Why file-name is not changed?

Thanks & Regards

It works for me. Says file-name's value is "test" (and not documented etc.).
Give a recipe starting from emacs -Q.

Hi Adams
Thanks a lot for your quick response.
After clean start with emacs -Q, the problem remain.
Below is my emacs-version:
Emacs 23.3.2 (i686-pc-linux-gnu, GTK+ Version 2.20.1) of 2011-04-06 on
wei-laptop

(Please use plain text for this mailing list, not HTML.)
I can reproduce the bug in Emacs 23.1, 23.2, and 23.3. It is a regression - it
works in Emacs versions prior to Emacs 23. It has been fixed again in Emacs 24
(which is not yet released), apparently.
You can downgrade to Emacs 22 or try using the Emacs 24 pretest. Or you can
find the fix they made or the Emacs 22 code for it and try using that in your
Emacs 23 session.

You do not say how you eval'ed the TWO expressions.
If you are in the scratch buffer and place the cursor at the end of the 2nd line, and hit C-j, emacs is only going to eval that line, which is the last sexp before the cursor.
Try putting your cursor at the end of this, and hit C-j:
(progn
(setq file-name "test")
(describe-variable 'file-name))
Or eval each line one after the other.
