Exploiting Labels in Structural Operational Semantics
Peter D. Mosses February 2005 |
Abstract:
Structural Operational Semantics (SOS) allows transitions to be
labelled. This is fully exploited in SOS descriptions of concurrent systems,
but usually not at all in conventional descriptions of sequential programming
languages.
This paper shows how the use of labels can provide significantly simpler and more modular descriptions of programming languages. However, the full power of labels is obtained only when the set of labels is made into a category, as in the recently-proposed MSOS variant of SOS Available as PostScript, PDF, DVI. |
