Abstract.A system of algorithmic algebras is formed based on a modified Glushkov’s computer model. Data are formalized and specified at the input and output of D-operators and thus the formal apparatus is based on data. Some properties of D-operators and of operations that form the signature of algebra are proved and setting up derived D-operators is shown to be possible. Refs: 7 titles.

Keywords: computer model, algebra of algorithms, data, algorithmic constructions, operation of algebra of algorithms, D-operators.
