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 {ISWIM},

{lazy} but {first-order}.

Ashcroft & Wadge , 1981.

They use a dynamic {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 {stream} of simple values,

every function as a {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.
