The language described in this paper is based on an attempt to combine relational and functional languages in a unified environment, which provides the best features of both approaches. Our goal was to design design a first order logic language, which allows to define both functions and procedures. Our language is a proper extension of functional languages enriched with somewhat constrained Horn clauses. The constraints are concerned with distinguishing between input and output parameter and sequencing of literals.

Abstract
The language described in this paper is based on an attempt to combine relational and functional languages in a unified environment, which provides the best features of both approaches. Our goal was to design design a first order logic language, which allows to define both functions and procedures. Our language is a proper extension of functional languages enriched with somewhat constrained Horn clauses. The constraints are concerned with distinguishing between input and output parameter and sequencing of literals.File in questo prodotto:
