.BET File Extension
What is a BET file?
Program file containing source code written in BETA, a modern object-oriented programming language; based off of Simula and developed within the Scandinavian School of object-orientation.
BETA includes powerful data abstraction features that allow programmers to easily design programs. The language structure also enables reusability of program designs and implementations.
BETA programs can be compiled using the BETA compiler, included with the Mjolner System development software package.
