alternate simple view
Country: United States
Designed 1992
Published: 1992

named after the Yerkes Observatory, an OOL based on a FORTH kernel with some major modifications. Originally known as NEON, developed and sold as a product by Kriya Systems from 1985-89. Several people from University of Chicago have maintained YERK since it's demise as a product. Because of possible Trademark conflict, they named it YERK.

from Rodriguez & Poehlman:
Neon was a commercial OOF, modeled after Smalltalk; when released into the public domain it was renamed Yerk. The object is not executed; it is parsed by the message word, which invokes or compiles the method. Added data structures include: class definition header, class list, method list, method stack, and object stack. Objects are statically allocated, but dynamically allocated memory can be "cast" as objects.
