Nature of problem:
This set of subroutines can serve as a basis for Monte Carlo programs simulating electron-photon cascades.

Solution method:
Every subroutine uses Monte Carlo techniques to simulate one of the following processes: bremsstrahlung, pair production, Compton effect, multiple Coulomb scattering. The subroutine DIST calculates the free path realized in the interaction.

Restrictions:
The subroutines are designed for energies corresponding to screening parameter gamma < 2. Versions of bremsstrahlung and pair production programs for full screening are also included. This means that the energy range is from several MeV to 10**11 MeV for air. In heavier media the energy interval is narrower because of the lack of validity of the Born approximation around the lower limit and the influence of the Landau-Pomerantchuk effect for the upper one.
