1486	 A Reprogramming Machine	 In this paper a description is given of a model programming system which is directed by a programming language and has a library for storing the user s items. Rules are given for transforming programs written in the language and for rearranging the items in the library so that they share their common parts. Some speculations are made about how the mechanical detection of common parts or patterns of library items could help a user to solve his problems and about the relationships between the behavior of the reprogramming machine and human intelligent behavior.
