The two-body nonleptonic decays of strange and charmed mesons are computed numerically in the framework of quantum chromodynamics in 2 dimensions using the 1/N/sub c/ expansion. It is shown that the amplitudes have no simple SU(4) algebraic properties. The decays of strange mesons are governed by the approximate ..delta..I = 1/2 rule which occurs as a consequence of the small bare masses of the s, u, and d quarks.
