Kemeny & Kurtz's Beginner's All-purpose Symbolic Instruction Code (Dartmouth, 1964) — designed so anyone could sit at a terminal and make the machine do something. Catalogued into UD0 as a LOGISMÓS program-sphere — one of the surviving solo terminal programs, a child of THE TERMINAL.

The Four Natures

each facet emerges by one of four natures

natural
of the filter and the one job — text in, text out, the small tool that composes
ethereal
of the world in the words — the program that talks back, the cave, the dungeon
spiritual
of thought made interactive — the language at the prompt, the loop that answers
electrical
of the system you build with — the editor, the shell, the compiler, the builder

The Program

born · what it does · the line

Born
Dartmouth · 1964

John Kemeny and Thomas Kurtz built BASIC and a time-sharing system so that every student, not just specialists, could use the computer.

What it does
compute, simply

A language plain enough that a beginner could type a few numbered lines and run them at once — computing for everyone, not the priesthood.

The line
BASIC → the home computer

Spread onto every home computer of the 1970s–80s; begat Visual Basic and the very idea of a beginner's language.

The Facets

Rendered, not invented — a cited history. BASIC is part of the documented record; authors are credited in the text and no source code or copyrighted text is reproduced. Lineage: Spread onto every home computer of the 1970s–80s; begat Visual Basic and the very idea of a beginner's language. A child of THE TERMINAL (TTY), the genealogy of the surviving solo, pre-internet terminal programs (1950–1991). Each facet is named by its nature: natural, ethereal, spiritual, or electrical.
