PPL is an interactive, extensible programming language incorporating data definition facilities and operator definition facilities. This manual introduces the various features of the language and serves as a practical reference document for its use. The manual is indexed and several appendices detail parts of the language in tabular form. PPL runs under the standard 1050 monitor series of the Digital Equipment Corporations PDP-10 and also under the TENEX monitor system of the Bolt, Beranek and Newman Corporation. A library of PPL extensions is available containing extensions for doing matrix, rational, formula, polynomial, complex, and vector arithmetics and, in addition, for manipulating lists, strings, and trees. The language is useful for manipulating data in a wide variety of application areas. Being interpretive and conversational, however, it is more well adapted toward personal and educational uses of computers using interactive terminals than it is for doing large institutional computing applications requiring long running times or voluminous input-output.
