'''BBC BASIC''' is an [[Interpreted Language|interpreted]] version of the [[BASIC]] programming language. It was developed by [[Acorn Computers Ltd]] when they were selected by the [[BBC]] to supply the computer for their [[BBC Literacy Project]] in 1981.

It was originally supplied on an installed [[ROM]] for the [[BBC Microcomputer]] which used a [[6502 microprocessor]]. When Acorn produced the [[Acorn Archimedes|Archimedes]] computer which used their [[ARM architecture family|ARM]] processor, further versions of BBC BASIC were produced. Acorn included a built in [[Assembly language|assembler]], first for the 6502 and later for the [[ARM2]] processor.

Initially the BBC specified compatibility with [[Microsoft BASIC]]. Acorn were already extending their earlier [[Atom BASIC]] to include [[structured programming]] constructs. Particularly on the later Archimedes computers as the memory constraints reduced, BBC BASIC incorporated a more complete set of structured programming constructs commonly found in the [[ALGOL 60]] group of computer languages.

Alongside Acorn's version of BBC BASIC on the Archimedes, third party companies produced [[compiled]] versions of the language. Development and support has continued after the demise of Acorn Computers Ltd for newer ARM based computers. BBC BASIC is now available on other platforms either for [[emulators]] such as on [[MS Windows]] or natively.
