Telescript (programming language)

Telescript is an agent-oriented programming language written by General Magic as part of the overall Magic Cap system. Telescript programs used a modified C-like syntax known as High Telescript and were compiled to a stack-based language called Low Telescript for execution. Low Telescript ran within virtual machine interpreters, or "Telescript engines", on host computers. The basic model of Telescript is similar to Java, and differs primarily in where the applications would run. Java was modelled to make it possible to download Java applications onto any platform and run them locally. Telescript essentially reversed this, allowing end-user equipment with limited capabilities to upload Telescript programs to servers to allow them to take advantage of the server's capabilities. Telescript could even migrate a running program; the language included features to marshal a program's code and serialized state, transfer it to another Telescript engine (on a device or a server) to continue execution, and finally return to the originating client or server device to deliver its output. General Magic had originally developed as a team within Apple Inc., and were spun off in 1990. When they began to generate some press buzz in 1992, Apple decided to enter the same market with their Newton tablet computer. General Magic were unable to find a niche within the market, and Telescript services were soon deprecated in favor of new products unrelated to mobile computing.
