ALGOL W

Procedural Language

ALGOL W is a programming language designed by Niklaus Wirth and C. A. R. Hoare in 1966 as a proposed, more disciplined successor to ALGOL 60, adding features such as records, dynamic arrays, and improved string handling that the ALGOL 60 committee ultimately declined to adopt into the main ALGOL line. Implemented at Stanford University, ALGOL W introduced strong influences on structured programming style and was the language several classic algorithms textbooks first presented their examples in. ALGOL W's design was a direct stepping stone to Wirth's own subsequent language, Pascal.

FAQs

Why was ALGOL W created?

ALGOL W is based on a proposal for ALGOL X by Niklaus Wirth and Tony Hoare as a successor to ALGOL 60 in the International Federation for Information Processing Working Group 2.1. When the committee decided that the proposal was not a sufficient advance over ALGOL 60, the proposal was published as A contribution to the development of ALGOL. After making small modifications to the language, Wirth supervised a high quality implementation for the IBM/360 at Stanford University that was widely distributed.

Preceded By

ALGOL, Programming Languages

General knowledge, not independently re-fetched: Niklaus Wirth and C.A.R. Hoare designed ALGOL W (1966) as a proposed evolutionary successor to ALGOL 60, before the ALGOL 68 committee took a more radical direction.

Predecessor Of

Pascal, Programming Languages

General knowledge, not independently re-fetched: after ALGOL W was not adopted as ALGOL's official successor, Wirth developed Pascal (1970) directly building on the ALGOL W design.
