BET file extension

A source file for the language BETA, an object-oriented programming language based off of Simula and developed by the Scandanavian School of Objection-Orientation. The BETA language has support for most of the common features in modern languages including a powerful data abstraction system which allows the programmer to forgo typing in his programming in order to rapidly develop a system. Further, the BETA language includes the ability of the programmer to re-use program designs and implementations that they've created before.
