AUTHORS: John G. Kemeny, Thomas E. Kurtz
HISTORY: John Kemeny and Thomas Kurtz created BASIC, the Beginner's All-purpose Symbolic Instruction Code, at Dartmouth College, where the first program ran on 1 May 1964. They wanted every student, not only science majors, to use a computer, and paired the language with the Dartmouth Time-Sharing System. In 1975 Bill Gates and Paul Allen wrote Altair BASIC, the first product of Microsoft, and by the 1980s almost every home computer booted straight into a BASIC prompt. Variable names carry their type: A is a number, A$ a string.
USAGE: The original line-numbered BASIC is historic, but it introduced a generation to programming. Its descendants live on in Visual Basic .NET, VBA, FreeBASIC and QB64, and in countless retro computing hobby projects.
