...SEMANTICS
First published in Bulletin of European Assoc. for Theor. Computer Science, no. 43, Feb. 1991, 264-284. Reprinted in Current Trends in Theoretical Computer Science, eds. G. Rozenberg and A. Salomaa, World Scientific, 1993, 266-292. This version contains slight modifications to reflect the one and only change in the definition of ealgebras that happened in the meantime, namely that the basic EA machine is deterministic; the explanation for the change is found in Subsection 2.7 in [Gu4].
