An example of the manipulation of directed graphs in the AMBIT/G programming language
Carlos Christensen · 1967
AMBIT/G (AMBIT for Graph Manipulation) is a language for the manipulation of directed graphs. The data on which an AMBIT/G program operates is displayed as an actual diagrammatic representation of a directed graph, and not some sequential encodement of a graph. Furthermore, AMBIT/G statements are themselves written as directed graphs. The programmer works in terms of these diagrams throughout the conception, composition, checking, and execution of an AMBIT/G program.
