Sorry for not mentioning my preparation for this question(and other questions). Before I ask a question, I usually try these methods: 1. Search the archives of comp.emacs and gnu.emacs.help. 2. Search on the web. 3. Use `icicle-Info-index'. 4. Use `icicle-search' on the manuals flattened with `Info-merge-subnodes'. 5. Search the Emacs FAQ. 6. Read the source code(but I'm not an Emacs Lisp guru). I had found it in (info "(elisp) Output Functions"), it says: Emacs detects such recursion and prints `#LEVEL' instead of recursively printing an object already being printed. For example, here `#0' indicates a recursive reference to the object at level 0 of the current print operation. But I don't understand. What does `object at level 0 of the current print operation' mean? > If you can find what you want by means other than using the indexes (`i'), > consider reporting an Emacs bug to improve the index, explaining how you tried > to find it. Thanks for your advice. I'll do that the next time. -- Best regards, Xue Fuqiao. http://www.emacswiki.org/emacs/XueFuqiao
