For an OoEnvironmentForPalm ? I got this update from http://cuiwww.unige.ch/langlist, where it says, "The Language List is an attempt to enumerate all known programming languages. It is maintained by Bill Kinnersley billk@cs.ukans.edu and is periodically published on comp.lang.misc. This service is provided in collaboration with Software Composition Group, University of Berne."
The entry for Neon says, "Neon - Charles Duff. An object-oriented extension of FORTH, for the Mac. Inheritance, SANE floating point, system classes and objects for Mac interfacing, overlays. Sold by Kriya Systems, 1985-1988. Modified, made PD and renamed Yerk.
