  The ground-state properties of the S=1 Haldane-Shastry model are studied
using a modified Lanczos algorithm and diagonalizing exactly small chains. We
find evidence that, as for the antiferromagnetic Heisenberg model, the spectrum
shows a gap, in contrast to the S=1/2 case. The correlation functions
<S^{z}(0)S^{z}(m)> decay exponentially for large m. We find that the
correlation functions for the Haldane-Shastry model decay faster than for the
Heisenberg model. We estimate the infinite system limit for the ground-state
energy, value of the gap and correlation functions.
