• The 5-dimensional spin-0 form of the Kemmer-Duffin-Petiau (KDP) equation is used to calculate scattering observables [elastic differential cross sections (dσ/dΩ), total cross sections (σ_<Tot>), and total reaction cross sections (σ_<Reac>)] and to deduce σ_<Tot> and σ_<pReac> from transmission data for K^++^6Li, ^<12>C, ^<28>Si and ^<40>Ca at several momenta in the range 488-714 MeV/c. Realistic uncertainties are generated for the theoretical predictions. These errors, mainly due to uncertainties associated with the elementary K^++ nucleon amplitudes, are large, which may account for some of the disagreement between experimental and theoretical σ_<Tot> and σ_<Reac>. The results suggest that the K^++ nucleon amplitudes need to be much better determined before further improvement in the understanding of these data can occur.
