Spam and its economic significance,istinguished ‘foot’ premise (returning arbitrary values). Both the logic and functional components permit LISP-like varying-arity and higher-order operators. The DATAFUN sublanguage of the functional component is shown to be preferable to relational encodings of functions in DATALOG. RELFUN permits

Function-defining conditional equations (or, footed clauses) and active call-by-value expressions (in clause premises) are integrated into first-order theories. Herbrand models are accomodated to relational-functional programs by not only containing ground atoms but also g

Functions can thus, relation-like, succeed or fail, enumerate values non-deterministically, return multiple values, and have non-ground arguments and values. Relations act like characteristic functions, permit functionally nested call-by-value arguments, and
