A-0 (or A0) is a programming language for the UNIVAC I or II[?], using three-address code instructions for solving mathematical problems. A-0 was the first language for which a compiler was developed. It was produced by Grace Hopper's team at Remington Rand[?] in 1952. Later internal versions were A-1[?], A-2[?], A-3, AT-3[?]. A-3 was released as ARITH-MATIC; AT-3 was released as MATH-MATIC.
