Form factors for pseudoscalar --> pseudoscalar decays of heavy-light mesons
are found in quenched lattice QCD with heavy-quark masses in the range of
approximately 1-2 GeV. The Isgur-Wise function, $\xi(\omega)$, is extracted
from these form factors. Results are in good agreement with $\xi(\omega)$
derived from CLEO measurements for B --> D*.
