Experience in standardization of programming languages for mini- and microcomputers

The article describes the experience of the scientific and technical commission for the unification of programming languages for mini- and microcomputers, created under the USSR State Committee for Science and Technology. The appearance in the early 1980s of little compatible models of computers initiated the task of revising the software used to ensure the portability of programs when switching to new types of computers. It was vitally important for programming control computers and simulators that simulate control for technological processes. The limitation of the task to the classes of mini- and microcomputers only was explained by the fact these classes computers were used mainly in simulators and control systems. The side results of the commission’s activities were more significant than the formal results.
