TABS-REPRESENTATION OF TASKS AND TASK GRAPHS

  • V.D. Ilyin

Abstract

The article describes the basics of construction and application of tabs-structures for representation of task constructive objects (named s-tasks) and s-task graphs. A tabs, representing a three-dimensional multilayered table with special cell types for the formation of tabs-structures, is studied as a basic element of a positional system for representation of s-tasks and s-task graphs.
The collection of procedures is defined for each type of tabs cells. A tabs- structure with prescribed rules of navigation is considered as a universal means of representation of various data structures (arrays, lists, etc.) and relations of order, belonging, etc. Tabs-structures serve as support of symbolic embodiment of ideas of developers of programming systems.
