Abstract : The SIRIUS language is intended for solving both numerical and analytical problems. The new language is realized by means of a two-phase translator. The first phase is a translation into an intermediate (Polish-nonparenthetic) language; the second phase is an interpretation from this language. Two modes of program execution are envisaged in the SIRIUS language: automatic programming and man-machine 'conversation' programming. Programs for problem solution include two types of information: initial nonalgorithmic and algorithmic; the first type includes formulas, equations, and relations written in the generally-used linearized notation; the second type includes a sequence of instructions expressed by Russian verbs in the imperative form. The SIRIUS language uses Russian, Latin, and Greek characters, numerials, true-false symbols, operation symbols, operators, and housekeeping words and symbols.
