Purpose

This language reference manual provides the programmer with information on the language components, declarations, statements, expressions, and program units of Extended ALGOL.

To assist application programmers in using ALGOL, the programming reference material is divided into two volumes. Volume 1 contains the Extended ALGOL developed for general use. Volume 2 contains extensions to ALGOL that are intended for specific products.

To use this manual, a programmer should be familiar with the general concepts of ALGOL programming or of another high-level structured programming language, such as Pascal.

This manual also describes the language components and program units of Extended ALGOL. Unless otherwise stated, the word ALGOL refers to Extended ALGOL.

Audience

This manual is intended for the applications programmer or systems analyst who is experienced in developing, maintaining, and reading ALGOL programs.

Notation Conventions

This manual contains reference information for each ALGOL feature, which can be accessed either through the index or the table of contents. Cross references are provided within each section. Declarations, statements, expressions, functions, and compiler control options are each presented in alphabetical order within their sections.
