Information processing apparatus for pattern editing using logic relationship representative patterns

摘要

A pattern editing apparatus includes a selector for selecting a plurality of patterns to be object patterns for an editing process. The plurality of patterns are displayed in a first area on a screen. The pattern selected by the selector is displayed in a second area on the screen. The apparatus also includes a provider, responsive to the selector, for providing a pattern for coupling the selected patterns displayed in the second area. The pattern coupling represents a flow chart processing relationship among the selected patterns. Also provided is a generator for generating a signal responsive to the absence of any pattern representing a flow chart processing relationship in the selected patterns, and an adder for adding the pattern representing the flow chart processing relationship as an object pattern of the editing process.
