  We determine the inclusive B --> Xc l nu branching fraction, the CKM matrix
element |Vcb|, and other heavy-quark parameters from a simultaneous fit to
moments of the hadronic-mass and lepton-energy distributions in semileptonic
B-meson decays, measured as a function of the lower limit on the lepton energy,
using data recorded with the BABAR detector. Using Heavy Quark Expansions
(HQEs) to order 1/mb^3, we extract BR_cenu=(10.61 +- 0.16(exp) +- 0.06(HQE))%
and |Vcb| = (41.4 +- 0.4(exp) +- 0.4(HQE) +- 0.6(th)) 10^-3. The stated errors
refer to the experimental, HQE, and additional theoretical uncertainties.
