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.

   ["Lucid: The Dataflow Language" by Bill Wadge
    and Ed Ashcroft, c. 1985].  ["Lucid, the
   Dataflow Programming Language", W. Wadge, Academic Press
   1985].
