Sub-topics

ALGOL 60 concept

The 1960 revision of ALGOL that introduced block structure, nested scoping, and BNF grammar notation. Never commercially dominant but described as 'the most important language you've never used' — its ideas are in every modern language.

ALGOL 68 concept

The 1968 revision of ALGOL — far more ambitious and complex than ALGOL 60. Introduced user-defined types, operator overloading, and orthogonal design. Considered ahead of its time but too complex for practical use. Influenced C and C++.
