The Free On-line Dictionary of Computing (19 January 2023):
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
constructors such as arrays or records. Iteration is
simulated with 'is current' and 'fby' (concatenation of
sequences). Higher-order functions are implemented using pure
dataflow and no closures or heaps.

and Ed Ashcroft, c. 1985]. ["Lucid, the
