Overview

ISO 8651-2:1988 - Information processing systems - Computer graphics - Graphical Kernel System (GKS) language bindings - Part 2: Pascal defines the standard Pascal language binding for the Graphical Kernel System (GKS). GKS itself is specified in a language‑independent way (see ISO 7942); ISO 8651-2 embeds that nucleus into the Pascal programming language (ISO 7185) so GKS can be used consistently in Pascal applications and libraries.

Key topics and technical requirements

Pascal binding specification: The standard prescribes how GKS abstract functions are represented as Pascal procedures and types, including naming conventions and required interfaces.

Procedure naming convention: All Pascal procedures for GKS begin with the letter “G”; common words in GKS names are abbreviated (see the standard’s abbreviation table).

Mapping strategies: Supports multiple mapping styles between GKS abstract functions and Pascal procedures:

Many‑one: Variant records and enumerated tag fields allow several related abstract functions to be represented by a single Pascal procedure.
One‑one: A mandatory one‑to‑one mapping option is provided for simpler or resource‑constrained implementations.
One‑many: Some inquiry functions are split into several Pascal procedures to provide more convenient access to subsets of returned information.

Data types and structures: Defines representation of GKS data types in Pascal, naming conventions for types, required constants, arrays, sets and record types, and implementation‑defined types.

Error handling and registration: Specifies a standard error handling function and rules for data records subject to registration.

Function coverage: Covers control, output, transformation, segment, input, metafile, inquiry and utility functions; annexes include data type ordering, metafile item types and example Pascal programs.

Practical applications and users

Software developers integrating GKS into Pascal applications for CAD, scientific visualization, technical plotting, and interactive graphics.

Library and runtime implementers creating GKS Pascal bindings or graphics kernels compatible across systems.

Compiler and tool vendors ensuring conformance to ISO Pascal (ISO 7185) when providing graphics libraries.

Academics and engineers maintaining legacy Pascal-based visualization code that relies on standardized GKS behavior.
