ALGOL W(ID:243/alg049)

Wirth and Hoare 

alternate simple view
Country: Switzerland
Designed 1966
Published: 1966
Genus: Algol Ws
Sammet category: Numerical Scientific

Wirth and Hoare in Europe 1965

Stanford 1966 Nikalus Wirth

Derivative of ALGOL 60. Introduced double precision, complex numbers, bit strings and dynamic data structures. Parsed entirely by operator precedence. Used call-by-value-result.

The other outcome (a minority report) of the IFIP Working Group to find a successor to Algol 60. Championed by the minimalist faction against the Algol X put forward by the supporters of Van Wijngarden.

In the histories (Dijkstra, Hoare, Wirth) that ridicule Algol 68, it is portrayed as the perfect child. In the alternative histories (vd Poel, Koester, Peck) it is seen as a recidivist step back to FORTRAN
