Abstract

FOL is a language for implementing file organizations. It is implemented in LPL, a list processing language that is an extension of PL/1. FOL presents the user with a convenient means for declaring the structure of records in a file. Either tree structured or graph structured files can be created and manipulated. The language treats records in a file as nodes in a list. The paper describes other file manipulation languages like APL and IDS. The data organization of FOL and the procedural language for declaring record structures and data manipulation commands are given.
