Описание (английский):

The language defined is different from those of previous PL/I standards, although substantially upward compatible, at the source program and semantic level. The differences are summarized in appendix A. Specifies the syntax and semantics of conforming PL/I programs. Defines a conforming processor (or conforming implementation) only in terms of those conforming programs. The definition is accomplished by specifying a conceptual PL/I machine which translates and interprets intended PL/I programs.

Overview

ISO/IEC 6522:1992 - Information technology - Programming languages - PL/1 general purpose subset - defines a standardized general-purpose subset of the PL/I programming language. The standard specifies the syntax and semantics of conforming PL/I programs by describing a conceptual PL/I machine that translates and interprets source programs. It is substantially upward compatible with earlier PL/I standards, with noted differences summarized in Appendix A. ISO/IEC 6522:1992 defines a conforming processor only in terms of those conforming programs and the machine behavior required to translate and interpret them.

Key topics and technical requirements

Concrete and abstract syntax: formal production rules and notations for PL/I text, identifiers, constants, comments and character sets.

Semantics: formal meaning of language constructs, expression evaluation, and runtime behavior as specified via the conceptual PL/I machine.

Metalanguage and tree notation: use of a metalanguage (tree concepts, node objects, production rules) to define language structure and transformation.

Translator model: separation of phases - low-level parse, high-level parse, validation, translation-unit completion and creation of abstract-equivalent trees.

Machine-state and initialization: formal definition of the PL/I machine state and initialization operations used to interpret programs.

Language constructs: declarations (data, variables, types), flow-of-control (IF, DO, SELECT, CALL, RETURN, GO TO), storage control, I/O (record and stream I/O, OPEN/CLOSE), ON-units (condition handling), format specifications and enquiry functions.

Implementation flexibilities and limits: treatment of implementation-defined features and permitted variations (quantitative restrictions, addressing, character sets, interrupts, I/O, etc.).

Validation and conformance: rules for validating translation units, completing declarations, and establishing conformance of programs and processors.

Applications and users

ISO/IEC 6522:1992 is primarily useful for:

Compiler and tool developers implementing PL/I compilers, interpreters or static analyzers who need an authoritative definition of syntax and semantics.

Legacy system maintainers and system integrators who must ensure consistent behavior across PL/I implementations.

Test and QA teams creating conformance test suites and validation tools for PL/I processors.

Academic and training purposes when teaching language design, parsing, or PL/I language features.

Standards bodies and archivists documenting the relationship to earlier PL/I standards and preserving language definitions.

Related standards

The standard notes compatibility and differences with previous PL/I standards (see Appendix A). It is published by ISO/IEC and complements other ISO programming-language specifications that use similar metalanguage and machine-based formalization.

Keywords: ISO/IEC 6522, PL/I subset, PL/1 general purpose subset, PL/I standard, programming languages standard, PL/I compiler, language specification, conforming implementation.
