Well, here's a chance to answer two questions at once. I haven't been able to find the "what's happening with PSI" question to reply to that, so... We (SoftQuad) are beta-testing PSI (Ozan Yigit's Portable Scheme Interpreter) now, and have ported it to the RS6000 (and we are about to port it again, since quite a few changes have been made since the last port). PSI is small, reasonably quick, and portable, and implements most of the r3.99rs, including a complete call/cc. It's been ported to various flavors of Unix, used with C++, ported to MS-DOS, ported to the Macintosh (minimally) and ported to Windows3.0 (again, minimally; no support for co-operative multitasking...yet). It should be available...er, sometime. Soon, I hope. I'm not authorized to speak for Ozan Yigit, or SoftQuad, for that matter, but SoftQuad does pay my salary, and I have been heavily involved in extending PSI. Regards, Dak -- David A.
