[comp.lang.forth] oo forths

rfl@oddjob.uchicago.edu (Bob Loewenstein) (07/26/89)

Speaking of object oriented forths...NEON is still alive and
well on my Mac II. There are a few basic additions to the kernel
(like a methods stack using another 68000 address register). The
rest is high level additions to forth. The additional stack
allows the use of local and named input variables.
Multiple cfa words can also be defined . Early and late binding are
supported. Instantiation in the the dictionary or on the heap.

The author of Neon went on to make Actor, an Object Oriented environment
for MS-Windows. Is Kriya Systems still supporting Neon? There were
many bugs reported in the early versions, which turned me away. I'm
interested in this if the support has been decent.

It might also be interesting for you to share some of the OO implementations
that you find useful, or cumbersome, via example. I'm sure many others
would be interested.
