Yerk

(After Yerkes Observatory) An {object-oriented}

language based on a {Forth} {Kernel} with some major

modifications. It was originally known as {Neon}, developed

and sold as a product by {Kriya Systems} from 1985 to 1989.

Several people at The {University of Chicago} have maintained

Yerk since its demise as a product. Because of possible

trademark conflict they named it Yerk, which is not an acronym

for anything, but rather stands for Yerkes Observatory, part

of the Department of Astronomy and Astrophysics at U of C.
