  Lattice results for heavy light matrix elements are reviewed and some of
their implications are very briefly discussed. Despite the fact that in most
cases the lattice results for weak matrix elements at the moment have only a
modest accuracy of about 20--30\% they already have important phenomenological
repercussions; e.g.\ for $V_{td}/V_{ts}$, $x_s/x_d$ and $B\to K^\ast\gamma$.
