Keywords: Particle physics, Elementary, Polarized particles, Inclusive and semi Inclusive deep inelastic, Scattering, Qed and, Electroweak radiative, Corrections, Structure functions, Higher order corrections, Experimental data, Processing.
Classification: 11.4.

Nature of problem:
First and higher order QED and electroweak radiative corrections to the inclusive and semi-inclusive polarized deep inelastic scattering; experimental data processing.

Solution method:
Numerical integration of analytical formulae.

Restrictions:
Only selective experimental cuts are possible. For O(alpha**2) order correction only leading contribution is calculated. Electroweak correction is calculated for longitudinally polarized target.

Unusual features:
The program uses PATCHY [1] and MINUIT [2] - both part of CERNLIB.

Running time:
The running time depends on the options used. For example: 1) calculation of the total QED correction takes about 4 seconds of the CPU time per one kinematical point; 2) calculation of electroweak+ O(alpha**2)+model for g2 not equal to 0 takes up to 300 seconds per one kinematical point.
