Nature of problem:
Event simulation of quantum chromodynamics in the process electron + positron -> virtual photon -> hadrons at moderate and very high energies, assuming the leading logarithm approximation and including the multiemission of QCD quanta.

Solution method:
Monte Carlo generation of emitted QCD quanta.

Restrictions:
Applications at low energy are limited to c.m.s. energies above 5-6 GeV, because of the physical approximations involved. At very high energy one may meet limitations associated with storage requirements.

Unusual features:
A random number generating routine should be added. The sample driving program requires the addition of externals, as specified.

Running time:
At a c.m.s. energy of 40 GeV, 0.02 s per event on average.
