I don't know, but I saw a scheme program on abcfd20 (can't remember where though) There are a number of semi-reasonable PD LISP systems available for the Amiga. A scheme (I suspect it's the same one), SIOD, and XLISP at least. XSCHEME may be available. Then there's AMXLISP, an XLISP extended to have access to the Amiga graphics interface. Finally, there's the one commercial LISP, Cambridge LISP. A table: mod comp s/a debug OOP libs intui AMXLISP x x x Cambridge x x Scheme x SIOD x XLISP x x XSCHEME x x x Mod -> It's a modern LISP (aka Common LISP or scheme) comp -> It has a compiler s/a -> Can generate stand-alone programs debug -> Has debugging facilities (never mind good ones!) OOP -> Object Oriented extensions libs -> access to the arbitrary libraries intui -> has clean intuition & graphics interface Cambridge LISP only had one very early release, and is probably an orphan now. It doesn't run properly on anything but 68000s. It's a dialect of LISP that wasn't used much in the US, and has important features from that dialect missing. Unless you want raw speed, this LISP is probably a waste of time. As you can tell, none of them do very well. SIOD, without an incredible amount of work, could be extended to include a compiler (I've done a proof-of-principle compiler for it already), and it should be possible to tweak it so you can generate stand-alone programs that use an amiga library. However, it's a subset of Scheme, so the modern x is only partial. To make up for that, full source is available, small and fairly clean. It's also very fast. For a speed contrast, there's XLISP & AMXLISP. Both are slow; easily being the slowest LISPs on the list. However, they're more complete than SIOD, and so make a better tool for someone wanting to get the feel of LISP. There is some attempt to look like Common LISP, the result being a nicer LISP than Cambridge. I haven't played with XSCHEME, and so don't know to how it compares in either of these areas. The Scheme is (last time I looked at it) a pretty straight-forward implementation of Scheme. If you've got the Abelson & Sussman's "Structuer and Interpretation of Computer Programs" and are looking for something to use with that, this is the correct choice. It's slower than SIOD, but faster than the X* LISPs. There are a number of freely distributable implementations of both Scheme & Common LISP. Maybe it's time to look into doing a port of one again. <mike -- He was your reason for living Mike Meyer So you once said mwm@relay.pa.dec.com Now your reason for living decwrl!mwm Has left you half dead

It also seems to be pretty fast. A primes example using streams took about 2 minutes on my profs Sun 3 running CScheme, but only about 35 seconds on my 18Mhz Lucas A1000. Unfortunately, it doesn't support Amiga specific stuff very well. Fortunately, source is included. Doug Kelly

I hadn't looked at XSCHEME before, and stated so in that posting. From having played with it this afternoon (on a DS3100), XSCHEME seems to be very nice. It didn't inherit the XLISP speed problems, and it's a much complete implementation than SIOD. Unfortunately, it has no hooks for getting to the Amiga-specific stuff, and the debugging environment seems primitive (at best). Note that this is _different_ from what I was calling Scheme, for which I've not seen source, but understand that it's 68K based assembler. <mike -- He was your reason for living Mike Meyer So you once said mwm@relay.pa.dec.com Now your reason for living decwrl!mwm Has left you half dead

All right. With all this talk of Lisp and Scheme, I got curious. I'd especially like to play with Scheme on my ami. But, where do I get it? According to a Fish xref I got from U of I pretty recently, there's a Scheme on FF149, AMXLisp 2.0 on FF181, and XLisp 1.7 on FF39 (sounds dusty). Is the above Scheme the one people are talking about, or is there a better one? -- -- Jeff (martens@cis.ohio-state.edu) Dan Quayle on education: "We're going to have the best educated American people in the world."

Is the above Scheme the one people are talking about, >or is there a better one? Wanna program in Scheeme, do you? Well, the most reliable source is Compu$erve.. They have the AmigaScheme package in two places... one in the AmigaTech libs under (i think) other lang's. Also, in C'$erv's Library's in Artificial Inteligence (sp)/programming. (under Scheme) So... use them. I use it a lot... I was just goofing off in Scheeme class today playing on the net... so... if anyone has any scheeme questions, dont hesitate to ask. jeremym@brahms.udel.edu -Come and take a ride on the Scheeme train...
