  Charged particle energy spectra in e+e- annihilation are compared with the
analytical predictions from the QCD evolution equation in the Modified Leading
Log Approximation. With the nonperturbative initial condition shifted down to
threshold as suggested by the Local Parton Hadron Duality picture a good
description of the data from the lowest up to highest available energies
results. The two essential parameters in this approach are determined from a
moment analysis. The sensitivity of the fit to the running of alpha_s and to
the number of active flavours (including a light gluino) is demonstrated. For
very high energies the theory predicts a scaling behaviour in certain rescaled
variables (``zeta-scaling''). The data show an approximate behaviour of this
type in the present energy range and come close to the predicted asymptotic
scaling function for the small particle energies.
