The ODP computational viewpoint describes the functionality of a system and its environment, in terms of a configuration of objects which interact at interfaces. Computational obj...
We propose a natural framework, called NF, which supports development of formal proofs on a computer. NF is based on a theory of Judgments and Derivations. NF is designed by observ...
This note describes Proof General, a tool for developing machine proofs with an interactive proof assistant. Interaction is based around a proof script, which is the target of a pr...
Modern applications provide interfaces for scripting, but many users do not know how to write script commands. However, many users are familiar with the idea of entering keywords ...
