TeX detected the command \protect\@. If you really wanted to^^J%
use that command, you should only use it in the middle of a^^J%
paragraph.^^J^^J%
But almost certainly you typed the command \protect\@\morehelp@e^^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%
\fi
^^J%
Enclose your code in \protect\makeatletter\protect\makeatother^^J%
pairs and TeX will be happy. But are you sure you should touch^^J%
LaTeX's internals? This is slippery ground%

I have reinserted the probable command sequence to be read again.
