This document is intended to describe the current design for computer programming language, Act-1. It describes the Actor computational model, which Act-1 was designed to support. A perspective is provided from which to view the language, with respect to existing computer language systems and to the computer system and environment under development for support of the language. The language is informally introduced in a tutorial fashion and demonstrated through examples. A programming strategy for the language is described, further illustrating its use.MIT Artificial Intelligence Laborator
