Reply to "Comment on `Ground-state properties of a spin-1 antiferromagnetic chain' "

We contrast, on the same figure, our phenomenological renormalization-group results on the $S=1\mathrm{}$ Heisenberg-Ising antiferromagnetic chain with results that we have recently obtained for $S=\frac{1}{2}$ and $S=\frac{3}{2}$. The different behaviors of integer- and half-integer-spin chains are revealed very clearly. This confirms the conclusion of our Communication.
