The main objectives of this paper are to present a multi-level file structure for natural or textual language, and a computer algorithm which logically associates elements of the presented file structure. These objectives are met by showing how the formalized data is mapped into a vocabulary that is amenable to automatic computation. This vocabulary consists of a set of indices which retain the syntactual association of the inputs. These sets of indices constitute a file organization which employs an associative list-type structure of the type utilized by Newell, Simon and Shaw in their Information Processing Language.
