    BASIC - Wikipedia, the free encyclopedia 1/22/12 1:10 PM BASIC From Wikipedia, the free encyclopedia BASIC is a family of general-purpose, high-level BASIC programming languages whose design philosophy emphasizes ease of use - the name is an acronym from Beginner's All-purpose Symbolic Instruction Code. The original Dartmouth BASIC was designed in 1964 by John George Kemeny and Thomas Eugene Kurtz at Dartmouth College in New Hampshire, USA to provide computer access to non-science students. At the time, nearly all use of computers required writing custom software, which Screenshot of Atari BASIC, an early BASIC was something only scientists and mathematicians tended to language for small computers do. The language and its variants became widespread on microcomputers in the late 1970s and 1980s, when it was Paradigm(s) unstructured, later procedural, typically a standard feature, and often actually built into the later object-oriented firmware of the machine. Appeared in 1964 BASIC remains popular to this day in a handful of highly Designed by John George Kemeny and modified dialects and new languages influenced by BASIC Thomas Eugene Kurtz such as Microsoft Visual Basic.
