I see. Sorry for my lack of knowledge about CVS Emacs. > The variable is not supposed to be used directly.

Sorry, I didn't give an example concrete enough. Here is the detail. 1. Assume that the buffer foo is in texinfo-mode and the buffer bar is in latex-mode. 2. Go to the buffer foo and type C-c C-f C-e. 3. As expected, @emph{} is inserted. 4. Place the cursor on @emph and type C-u C-c C-f C-e. 5. At this point, (char-to-string (with-syntax-table (TeX-search-syntax-table ?{ ?}) (char-syntax ?@))) returns "\\". This is OK. 6. Go to the buffer bar. 7. Evaluating (char-to-string (with-syntax-table (TeX-search-syntax-table ?{ ?}) (char-syntax ?@))) gives "\\", which is unwanted. The char `@' should not have escape syntax in latex-mode buffer. The item 7 is what I tried to point out in the paragraph >> In addition, the way the function TeX-search-syntax-table treats the >> variable TeX-search-syntax-table does not seem good to me.

In other words, the function TeX-search-syntax-table should initialize the variable every time if a single syntax table is to be shared between all the buffers of dirrerent modes.
