ISO/IEC 10279:1991/Amd 1:1994

Information technology — Programming languages — Full BASIC — Amendment 1: Modules and single character input enhancement

Establishes the syntax of programs written using individual character input, or modules, or both; the semantic rules for interpreting the meaning of a BASIC program that uses individual character input, or modules, or both; errors and exceptional circumstances to be detected and also the manner in which such errors and exceptional circumstances are to be handled.

Overview

ISO/IEC 10279:1991/Amd 1:1994 is an important amendment to the international standard for Full BASIC programming language, focusing on enhancing the language with Modules and Single Character Input capabilities. Developed jointly by ISO and IEC under the ISO/IEC JTC 1 technical committee, this amendment ensures standardized syntax and semantics for programs utilizing individual character input and modular programming in BASIC. The amendment supports a broad range of automatic data processing systems, enhancing the interchangeability and portability of BASIC programs across platforms.

This enhancement builds upon the original ISO/IEC 10279:1991 standard, aligning with American National Standard X3.113A-1989, and aims to define clear rules for program structure, error handling, and runtime semantic interpretation.

Key Topics

• Syntax Enhancements
  Defines precise syntax rules for writing BASIC programs that use:

  • Individual character input (allowing fine-grained input handling)
  • Modular programming structures (enabling reusable code components)

• Semantic Rules
  Specifies how programs using these new features should be interpreted, ensuring consistent execution behavior across compliant implementations.

• Error Handling and Exceptional Circumstances
  Details the detection of errors related to modules and character input, along with standardized procedures for handling exceptions to improve program robustness.

• Conformance Modules
  Introduces four new conformance modules catering to:

  • Individual Character Input Module and Subset Module
  • Modules Module and Subset Module
    These modules help implementers verify compliance with both the amendment and the original Full BASIC standard.

• Interoperability Focus
  Supports seamless program interchange across different systems, making it easier for developers to port BASIC programs that leverage modules and character input.

Applications

• Software Development
  Enables developers to write more modular and maintainable BASIC programs, enhancing code reuse and clarity.

• Legacy Systems Modernization
  Facilitates updating older BASIC applications by standardizing the handling of character input and modules, helping to integrate legacy code into modern environments.

• Cross-Platform Compatibility
  Assures that BASIC programs with modular structures and character input behave consistently on various hardware and software platforms, reducing vendor lock-in.

• Embedded and Automated Systems
  The enhanced character input handling allows for better control in systems requiring precise and immediate input processing, such as embedded controllers or automation scripts.

Related Standards

• ISO/IEC 10279:1991
  The base Full BASIC programming language standard to which this amendment is applied.

• ANSI X3.113A-1989
  The American National Standard Addendum from which the amendment derives its technical content on modules and character input.

• ANSI X3.113-1987
  The original ANSI BASIC standard referenced in the amendment for conformance subsets.

• ECMA-116
  ECMA's BASIC standard, mentioned for comparison, although it does not cover modules or individual character input like this amendment.

Summary

ISO/IEC 10279:1991/Amd 1:1994 establishes essential extensions to the Full BASIC programming language, focusing on modularity and enhanced input capabilities. By defining sound syntax, semantic interpretation, and error handling rules, this amendment promotes interoperability and maintainability of BASIC programs. It is especially valuable for developers working in multi-platform environments, supporting legacy code integration, and creating robust data processing applications in BASIC.

Foreword
ISO (the International Organization for Standardization) and IEC (the Intcr-
\
national Electrotechnical Commission) form the specializcd System for
worldwide standardization. National bodies that are members of ISO or IEC
participate in the development of International Standards through technical
committees established by the respective organization to deal with particular
fields of technical activity. ISO and IEC technical committees collaborate in
fields of mutual interest. Other international organizations, governmental and
non-governmental, in liaison with ISO and IEC, also take part in the work.
In the field of information technology, ISO and IEC have established a joint
technical committee, ISO/IEC JTC 1. Draft International Standards adopted by
the joint technical committee are circulated to national bodies for voting. Publi-
cation as an International Standard requires approval by at least 75 % OP the
national bodies casting a vote.
