K Ji zba Nested arrays in APL together with other enhancements make it possible to build LISP-like (and PROLOGlike) applications. This paper describes some of the techniques for dealing with structures such as TREES and NETWORKS. Examples illustrate possible applications in the field of artificial intelligence. TREES A vector can be thought of as a rooted tree (for definitions of these terms, see a textbook on graph theory such as [11). For example, the vector of integers could be represented by a tree diagram: VECTOR: 1 2 3 4 TREE: Conclusion As described before, the system is now complete and performs logic inferences according to expectations. The syntax is more compact than PROLOG's, and the number of rules and axioms for a given system is somewhat smaller. In the case of our example, a total of 24 rules and 174 axioms contain all the information. Quite complicated questions on genealogy and relationship of the Greek gods
