This article describes the software creation and development of the computer. Fortran 4 was chosen for scientific and technical problems. They named the language based on Fortran 4 language RTL (Fortran- real time language) treated the allocation of programs in the memory, different kinds of record commands in registers, and instruction structures in memory. It treated the principles of control units and developed an acquisition of some system statistics. Programming in the Fortran-like language increased the coding productivity fivefold in comparison to coding with an ordinary computer language.
