- Algol d
algol d language [“A Proposal for Definitions in ALGOL”, B.A. Galler et al, CACM 10:204-219, 1967].
- Algol n
algol n language A successor to ALGOL 60 proposed by Yoneda. (1994-11-24)
- Algol w
algol w language A derivative of ALGOL 60. It introduced double precision, complex numbers, bit strings and dynamic data structures. It is parsed entirely by operator precedence and used the call-by-value-result calling convention. [“A Contribution to the Development of Algol”, N. Wirth, CACM 9(6):413-431, June 1966].
