ALGOL D, also known as ALGOL 68 Revised or ALGOL 68-R, is a programming language that is an extension of the original ALGOL 68 (ALGOrithmic Language 1968). It was developed by the International Federation for Information Processing (IFIP) Working Group 2.1 with the aim to refine and standardize the ALGOL 68 language specification.
ALGOL D is a high-level, general-purpose programming language that combines imperative and functional programming paradigms. It provides a wide range of features and constructs, including strong static typing, flexible syntax, dynamic memory allocation, and support for modular programming. It was designed to be machine-independent and portable, allowing programs written in ALGOL D to be easily executed on different computer architectures.
The language incorporates various improvements over its predecessor, ALGOL 68. It introduces additional operators, more precise type system, improved error handling mechanisms, and enhanced support for input/output operations. ALGOL D also includes a powerful string manipulation library, advanced control flow constructs, and a comprehensive set of mathematical and logical operators.
ALGOL D has been used in various fields of computer science, particularly for the development of scientific and numerical computation applications. Although it has gained popularity among researchers and enthusiasts in the 1970s and 1980s, its usage has declined over time with the emergence of more modern and popular programming languages. Nonetheless, ALGOL D played a significant role in the evolution and advancement of programming languages, contributing to the development of subsequent generations of programming languages.
