Indeed. Our friend Henrique Lopes Cardoso reported this a little while
back. It's already been fixed and the correct behavior will appear in
7.1RC1 .

The Jess manual documents <> as returning TRUE if the first argument

equal. (I can envisage the implementation being a copy of the
implementations of <, <=, >, >= and =, running the test for all
neighbours.)
Either the documentation or the implementation should be fixed.
It's difficult to see the general usefulness of the implementation
for more than 2 arguments. The described semantics seem to be a
little more useful.
Kind regards
