Abstract A search for the production of direct photons in S+Au collisions at 200\cdotA GeV has been carried out in the CERN-WA80 experiment. For central collisions the measured photon excess at each p_T, averaged over the range 0.5 GeV/c  \leq p_T \leq 2.5 GeV/c, corresponded to 5.0\% of the total inclusive photon yield with a statistical error of \sigma_{\rm stat}=0.8\% and a systematic error of \sigma_{\rm syst}=5.8\%. Upper limits on the invariant yield for direct photon production at the 90\% C.L. are presented. Possible implications for the dynamics of high-energy heavy-ion collisions are discussed.
