  The trigonometric KZ equations associated to a Lie algebra \g depend on a
parameter \lambda in \h where \h is a Cartan subalgebra of \g. A system of
dynamical difference equations with respect to \lambda compatible with the KZ
equations is introduced in Tarasov and Varchenko. We prove that the standard
hypergeometric solutions of the trigonometric KZ equations associated to sl_N
also satisfy the dynamical difference equations.
