Absys was an early declarative programming language from the University of Aberdeen.[1] It anticipated a number of features of Prolog such as negation as failure, aggregation operators, the central role of backtracking[2] and constraint solving.[1] Absys was the first implementation of a logic programming language.[1]

The name Absys was chosen as an abbreviation for Aberdeen System.[1]
