  We present measurements of the branching fractions and a search for
CP-violating charge asymmetries in charmless hadronic decays of B mesons into
two-body final states of kaons and pions. The results are based on a data
sample of approximately 23 million BB(bar) pairs collected by the BABAR
detector at the PEP-II asymmetric B Factory at SLAC. We find the following
branching fractions: BF(B0-->pi+pi-)= (4.1+/-1.0+/-0.7) x 10^{-6},
BF(B0-->K+pi-)=(16.7+/-1.6+/-1.3) x 10^{-6},
BF(B+-->K+pi0)=(10.8^{+2.1}_{-1.9}+/-1.0) x 10^{-6},
BF(B+-->K0pi+)=(18.2^{+3.3}_{-3.0}+/-2.0) x 10^{-6},
BF(B0-->K0pi0)=(8.2^{+3.1}_{-2.7}+/-1.2) x 10^{-6}. We also report the 90%
confidence level upper limits BF(B0-->K+K-) < 2.5 x 10^{-6}, BF(B+-->pi+pi0) <
9.6 x 10^{-6}, and BF(B+-->anti-K0K+) < 2.4 x 10^{-6}. In addition, charge
asymmetries have been measured and found to be consistent with zero, where the
statistical precision is in the range of +/-0.10 to +/-0.18, depending on the
decay mode.
