LUCID
1. Early query language, ca. 1965, System Development Corp, Santa Monica, CA. [Sammet 1969, p.701]. 2. A family of dataflow languages descended from ref="module.php?name=Lexikon&file=search&eid=1&query=ISWIM">ISWIM, ref="module.php?name=Lexikon&file=search&eid=1&query=lazy">lazy but ref="module.php?name=Lexikon&file=search&eid=1&query=first-order">first-order. Ashcroft & Wadge , 1981. They use a dynamic ref="module.php?name=Lexikon&file=search&eid=1&query=demand driven">demand driven model. Statements are regarded as equations defining a network of processors and communication lines, through which the data flows. Every data object is thought of as an infinite ref="module.php?name=Lexikon&file=search&eid=1&query=stream">stream of simple values, every function as a ref="module.php?name=Lexikon&file=search&eid=1&query=filter">filter. Lucid has no {data constructor}s such as {array}s or {record}s. {Iteration} is simulated with ' is current' and ' fby' (concatenation of sequences). Higher-order functions are implemented using pure dataflow and no closures or heaps. ["Lucid: The Dataflow Language" by Bill Wadge and Ed Ashcroft, c. 1985].
