Do you mean Grafcet ?
I remember learning it in the early 80s, mainly to program PLCs.

Yes that was it - Grafcet, but did it have language application or were it "only" a design system..? IIRC 5-series of Siemens Simatics did have something that were similar to Sequential Function Charts (if so name were certainly different, since it were before standard as Simatic 5 introduced in the 1979 ... wikipedia is a friend Graph5)..
