Is there a SCHEME interpreter / compiler available, for use under UNIX? It need not be fancy, but I would prefer that it not be unbearably slow. Thanks. Luddy Harrison

Chez Scheme is a very good implementation of Scheme for 4.2BSD UNIX
Vaxes. Scheme programs run faster in Chez Scheme than corresponding
Lisp programs in Franz. Chez Scheme has some nice bells and whistles,
too, like arbitrary-precision rational arithmetic, floating point
arithmetic, clean user interface, engines (for implementing multi-
processing), user-programmable exception handlers, and other stuff.
Chez Scheme is about one year old now, and among the 12 or so places
actively using it there have been very few bugs reports or other
complaints. We are using it here at Indiana to teach over 400
students a year in 5 or 6 different courses (all on one Vax 785!)
It is distributed by "Cadence Research Systems" to US universities
for a $400 one-time fee to cover legal, material, and time costs
($1000 for US companies). There is a license. The distribution
includes system and documentation. I developed Chez Scheme initially
while I was a graduate student at UNC Chapel Hill.

There's also a port of MIT's version of Scheme (presumably the original) that runs under Vax/Unix, jmiller%oz.ai.mit.edu@mit-mc apparently ported it. It's been around since at least 1981 when I was a freshman there, but that's about all I know. -- - Ralph W.

Thanks for the many responses to my query. I will post just two of them, from Kent Dybvig (University of Indiana) and J. Greg Davidson (Virtual Infinity Systems, San Diego -- Mr. Davidson's response comes to me via Vincent Broman, Naval Ocean Systems Center, San Diego) which included descriptions of all the SCHEME systems about which I recieved information. -Luddy Harrison > >Chez Scheme is a very good implementation of Scheme for 4.2BSD UNIX >Vaxes.

I believe this notice was also sent to the Scheme-Flamers mailing list "somewhere" at MIT (sorry, I just don't remember exactly). Implementation: PC Scheme Developed by: Texas Instruments Computer Science Lab Supported by: Texas Instruments Digital Systems Group Hardware: TI Professional and TI Business-Pro Computers, IBM PC, PC/XT, PC/AT and IBM compatibles Operating Systems: MS(tm)-DOS 2.1 (PC-DOS) or better (at least 320K, dual floppy) Price/Availability: List price - $95, available in December 1985 Implementation: Incrementally compiled to byte-codes Intended Use: Education, research, and support of AI software on PCs PC Scheme is an implementation of Scheme for the TI Professional Computer and IBM(r) Personal Computer families. The product consists of an optimizing compiler, a byte-code interpreter, extensive run time support, an interactive, display-oriented editor, a language reference manual, and a user's guide. The system was developed on the TI Professional Computer in Scheme itself, with critical run time routines coded in C and assembly language for increased performance. PC Scheme provides all the essential and most of the optional features of the Revised Revised Report on Scheme. It fully supports the dialect used in the book "Structure and Interpretation of Computer Programs" by Abelson and Sussman as well as many extensions developed at Indiana University, MIT, and TI. These include first-class engines and environments and an experimental, object-oriented programming system with dynamic multiple inheritance called SCOOPS. Data type support includes symbols, lists, vectors, strings, fixnums, bignums, flonums (64 bit IEEE floating point), characters, closures, continuations, environments, and I/O ports. Evaluation is based on incremental compilation to byte-coded "virtual machine" code which is emulated using threaded code techniques. Informal benchmarks, including some of the Gabriel set, show PC Scheme programs to be about 3-10 times faster than interpreted IQLISP(tm) and 2-4 times faster than interpreted Golden Common LISP(tm). PC Scheme is oriented primarily towards compilation and fast execution rather than extensive source-level debugging. However, it does provide trace and breakpoint facilities and an interactive Inspector with commands to display and manipulate call stack frames and lexical environments, edit variable bindings, trace back through a chain of procedure calls, and evaluate expressions in the environment of a breakpoint. All user-correctable errors trap to the Inspector. The display-oriented editor supplied with PC Scheme is a subset of EDWIN, a version of EMACS written by the Scheme project at MIT and adapted to PC Scheme by TI. 512K bytes of RAM are required to use EDWIN. Other PC Scheme run time support includes windowed screen input/output, graphics, a pretty-printer, and an editor of in-memory list structures. Compiled files can be converted to a "fast-load" format to speed up load times. Files containing variable definitions can be "autoloaded" on demand. A Winchester disk minimizes the inconvenience of autoloading, but is not required. Documentation includes a 286-page language reference manual and a 93-page user's guide. Neither manual attempts to be a tutorial manual for Scheme itself. PC Scheme is being used extensively within Texas Instruments and is the basis for future releases of TI's PC-based AI products, including Arborist (tm) and the Personal Consultant Plus (tm). It is currently in use at approximately 25 universities in various settings (classes, experimentation, evaluation). PC Scheme may be ordered beginning November 15 for shipment in December. To order, write to Texas Instruments, MS 2151 12501 Research Blvd., Austin, TX 78759 and ask for TI Part number #2537900-0001. You may also order by telephone using MasterCard or VISA by calling 1-(800)-TI-PARTS. Questions or comments on the product may be directed to the address given above.
