Abstract
The inclusive production of prompt photons with energy above 10 GeV
is measured using the OPAL detector in hadronic 
decays at LEP.
Minimal isolation cuts were imposed upon the prompt photons.
The production rate and energy spectrum of prompt photons
are found to be in agreement with QCD predictions for the
quark-to-photon fragmentation function.
