Does anybody know what the status > of this project is, or any details about the actual code? > (Is it portable? What machines does it run on?, etc.) The code is written in reasonably portable C. I know for sure it runs on IBM PClones, Macs, and Amigas. The code is posted and occasionally being discussed on BIX (Byte Information eXchange). The latest version (as far as I know) is *very* preliminary, my copy is version 0.07. A handful of bugs and lack of reasonable error messages makes it rather unsuitable for real work at the moment, but a new and improved version is rumoured to be in the works (though David Betz has been curiously silent about it lately). XScheme is based on a bytecode compiler. Apart from that, its distinguishing feature is its object oriented extensions, similar to those of XLisp. - Harald Hanche-Olsen Division of Mathematical Sciences hanche@norunit.bitnet The Norwegian Institute of Technology
