Deflation method equilibrium equations of multispan multistorey constructions are reduced to the system of algebraic equations having a 5-block structure, each block size being equal N. It is necessary to construct 5 NxN-size matrixes and 1 N-size vector as input data in solving the system during forward motion. Forward motion realization requires 1 NxN-size matrix inversion operation, 6 matrix by matrix multiplications operations, 3 matrix by vector multiplication operations for each i, when 5 matrixes and 1 vector have been prepared.

The algorithms realized with Borland Pascal IDE storing in RAM 4, 3, and 2 NxN-size arrays, 4 N-size arrays are described in the paper. NxN-size array number decrease makes for XMS access number increase.
