Technologies de l'information — Langages de programmation, leurs environnements et interfaces logiciel système — Langage de programmation APL étendu

This International Standard defines the programming language APL and the environment

in which APL programs are executed. Its purpose is to facilitate interchange and promote

portability of APL programs and programming skills. This International Standard specifies

the syntax and semantics of APL programs and the characteristics of the environment in

which APL programs are executed.

It also specifies requirements for conformance to this International Standard, including the

publication of values and characteristics of implementation properties so that conforming

implementations can be meaningfully compared.

This International Standard does not specify:

? implementation properties that are likely to vary with the particular equipment or

operating system used;

? required values for implementation limits such as APL workspace size or numeric

precision;

? the data structures used to represent APL objects;

? the facilities available through shared variables.
