      The program is intended to solve multidimensional problems in gas dynamics using small perturbation method. The problem is linearized based on the main 1-D solution and linear perturbations are represented as angular variable Fourier series. A numerical procedure is implemented for combined calculations of exact solutions and harmonic amplitudes in multi region problems using the "viscosity cross" scheme. The program is written in FORTRAN within the 1-D Complex. The problem formulation and program organization are described. Numerical results are given which are compared to analytical ones.
