All ALGOL-Derived Languages

ALGOL-Derived Languages groups programming languages descended from or forming part of the ALGOL family tree, sharing the block-structured, procedural design that ALGOL introduced. ALGOL 58 was the original International Algorithmic Language proposal that led to ALGOL 60. ALGOL 68 was a later, more formally specified revision, and ALGOL W was Niklaus Wirth's own simplified alternative to ALGOL 68, developed at Stanford as a teaching and research language. Wikipedia's Generational list of programming languages places each of these three under the ALGOL entry in its own genealogy of programming languages, tracing lineage by the ancestor language with the strongest influence. The three languages differ in scope and formality but share ALGOL's core commitment to structured control flow, lexical scoping and readable procedural syntax, distinguishing them from the machine oriented languages that preceded ALGOL in the 1950s.
