A code to solve 1-D continuum mechanics problems is described, allowing to account the following physical processes: gas dynamics, elastoplastic deformation on the basis of Prandt1-Reiss plastic flow laws, explosive detonation, breakoff and radial fracturing, diffusion-approximated heat conductivity. Finite- -difference walkthrough pseudo-viscosity method ("CREST"-scheme) is used for numerical solution of the gas dynamics system. Radial fracturing, evaporation, melting and explosive detonation are realized in the program through the equation of state.
      The program is block-structured and has dynamic memory allocation. The program computer complex linking is made depending on the type of symmetry of the problem being computed. Problem capabilities are demonstrated by computing 6 test problems.
