(A French acronym for Synchronous real-time Lucid). Real-time dataflow language for synchronous systems, especially automatic control and signal processing. A Lucid subset, plus timing operators and user-defined clocks.

Designed for automatic control applications. It is based on the idea that automatic control engineers use to analyse, and specify their systems in terms of functions over sequences (sampled signals). It thus seems both safe and cost effective to try to compile directly those descriptions into executable code. A lot of work has been done, so as to get efficient compilation, and also in formal verification. The language has been used in nuclear plant control, and will be used in aircraft control.

But its lustre gleamed upon the ceiling; the exquisite texture of its wings brushed against that earthly medium; and a sparkle or two, as of stardust, floated downward and lay glimmering on the carpet.
This has allowed me to further extend my work with lustres as well as to work with enamels and to investigate the making of decals.
The mass-produced versions used painted on patterns, but Goddard preferred to use reducing lustres which gave a far better finish and were greeting by the leading art journal, the Connoisseur, as 'jewel-like in their brilliance and lustre'.
But here was Graham Oldroyd, student of Alan Peascod, who exposed his students to lustres, a revelation to Stern; Oldroyd and Peascod had studied Arabic lustre with Professor Said El-Sadr, in his studio in Fostat, Cairo, Egypt and also with Alan Caiger-Smith.
