**Abstract**

We report on a new environment developed and implemented inside the Nuprl type theory that facilitates proving theorems about partial functions. It is the first such automated type-theoretic account of partiality. We demonstrate that such an environment can be used effectively for proving theorems about computability and for developing partial programs with correctness proofs. This extends the well-known proofs as programs paradigm to partial functions.
