The \observational content" of geometric logic is discussed and it is proposed that geometric logic is an appropriate basis for a Z-like speci cation language in which schema...

We present a Language Prototyping System that facilitates the modular development of interpreters from independent semantic buildks. The abstract syntax is modelled as the fixpoint...
