        TeX detected the command \protect\@. If you really wanted to^^J%

        paragraph.^^J^^J%

        (maybe hidden in a previous macro definition).^^J%
        TeX did not recognize the remaining characters^^J%
        as a part of the command name, because @ is not^^J%
        a letter and usually cannot go in a control sequence.^^J%
        \expandafter\ifx\csname @\morehelp@e\endcsname\relax
          On the other hand \protect\@\morehelp@e\space is not even^^J%
          a valid command name, so maybe I'm wrong here.^^J%

        ^^J%
        Enclose your code in \protect\makeatletter\protect\makeatother^^J%
        pairs and TeX will be happy. But are you sure you should touch^^J%
