We describe some features of the tactic language implemented in the theorem prover Ergo 5. This is a variant of the generic tactic language Angel. We have adapted the language by changing the semantics of its parallel composition operator, the operator by which diierent tactics are applied to diierent branches in a proof tree. The paper includes a denotational semantics for this operator, and a collection of derived tactics which use it, together with a collection of algebraic laws which they… CONTINUE READING
