We present updated results from the CLEO collaboration from two studies of B meson decay to charmless hadronic final states. In the first analysis, we combine data from the CLEO II and CLEO III detectors to provide final measurements of thirteen two-body decay modes. In the second, the combined CLEO II and CLEO II.V data set is used to determine the momentum spectrum and branching ratio in the inclusive process ; with a more powerful analysis technique than was previously used. For the momentum range GeV/c , we find a branching ratio, , of [4.6± 1.1± 0.4± 0.5] × 10–4. The uncertainties are statistical, systematic, and due to subtraction of charm-decay background, respectively.
