This paper reviews the results and physics of two contributed papers to ICHEP94. Both papers relate to charm meson hadroproduction at Fermilab fixed target energies. The first (from E769) addresses the total forward cross section for charm mesons (D{sup {plus_minus}} and D{sub s}{sup {plus_minus}}) produced by {pi}{sup {plus_minus}}, K{sup {plus_minus}}, and proton beams. The second paper (from E791) deals with the asymmetries in the differential cross sections for charged D mesons produced in the forward direction by {pi}{sup {minus}} beam. The physics most directly related to the results of the E769 paper are the gluon distributions in the incident hadrons as well as perturbative QCD calculations of charm quark production and the charm quark mass. The E791 results address the details of the hadronization process after production of the charm quarks.
