First Measurement of the Charm Structure Function of the Photon              
        in Deep Inelastic Electron-Photon Scattering at LEP                    
  
 The inclusive production of charged D* mesons in deep inelastic               
 electron-photon scattering has been used to extract the charm                 
 structure function of the photon in the kinematic range                       
 0.0014 < x < 0.87 and 5 GeV^2 <Q^2 < 100 GeV^2. The data were                 
 taken with the OPAL detector at LEP at e+e- centre-of-mass                    
 energies of 183 and 189 GeV. The result is compared to an NLO                 
 perturbative QCD calculation.
