interesting! Erik, I've heard of Lisp (alias Lots of Infuriating, Spurious Parentheses) implemented on the first NOVIX chip, which ran faster than any LISP engine, Have you heard of a forth implemented on a Lisp engine that ran faster than any (other, more than 4-bit) implementation of Forth?

Well, even if he had heard of it, that wouldn't make it so. "ran faster" is vague and very subjective especially with lisp. A sun 4 can beat a lisp machine on small jobs simply because its processor is faster. On other code the lisp machine will be faster because it can do garbage collection on the fly. Look, different languages are good for different things. Real programmers decide based on the application, machine, and what is available which language to use. All that this discussion has said so far is that forth can be written in lisp and lisp can be written in forth. Big deal! -- Bill <bouma@cs.purdue.edu> || ...!purdue!bouma

Big Deal? Do you know how elegantly it can be done? Does that matter? Sure
it does. abstract languages like lisp, and forth (sort of) are amazingly
expressive, and it is no useless fact that they can implement one another.

C is assembler, so poorly implemented that it takes six MONTHS to port a crummy version of the compiler (This time period is from the paper on pcc, the portable C compiler). Forth is not Lisp. The only thing Forth has in common with Lisp is that both are completely unlike anything else. Forth has similar strengths to Lisp. One interesting strength that it does NOT share with Lisp is that Forth will run usably fast on hardware that I can afford to put in my home. Hardware is only inadequate when it won't run fast enough to do the job at hand. If your software development tools can't be used to develop code for my hardware, then there's something wrong with your tools. CPU's don't exist for the sake of making compilers work well; it's the other way around. Forth avoids the headaches and overhead of garbage collecting while giving the programmer similar tools. This means that Forth will give better performance than Lisp no matter what the hardware (with the possible exception of "Lisp engines"). C, of course, is a compact notation for assembler. The designers had only that goal in mind -- they thoughtlessly made the language complex to parse, and difficult to write debuggers for. Systems designers see the need for a seamless environment -- the C shell is an example of what I mean. Everyone understands the desire to have the command-level language and the programming language look alike. Forth solved this problem years ago by having the two languages BE THE SAME THING -- you may issue system-level commands or write code at any Forth prompt. Forth is internally MUCH CLEANER that a typical Lisp interpreter. There is no need for "syntactic sugaring" in Forth, a trend in the Lisp world that makes parsers more complex, more opaque, and more difficult to debug. I would concede that Forth is something like Scheme -- a very simple Lisp-like interpreted language whose approach is one of high performance and minimalism. Finally, Charles H. Moore, the inventor of Forth, has never been an astronomer. -Marc "Rebel Without A Compiler" de Groot "I don't CARE about small machines." -Richard Stallman, on being informed that GNU Emacs won't fit on an 80286 UNIX box because elisp is too big. -- Marc de Groot (KG6KF) These ARE my employer's opinions!

It is just that everyone has known this for a long time. SO why have there been 5 posts simply stating that fact? I would love to see some posts talking about how this can elegantly be done. Tell me how the architecture of the Novix chip allows one to efficiently implement lisp. That may make for some interesting reading.

I am one of those people who is really excited by FORTH but I can't seem to get enough hard core information about real programming experiences in FORTH. I am trying to develop a non-trivial medical information system application and have been seriously contemplating using HS/FORTH (I own an IBM PC/XT) but have been afraid to. I am worried about committing myself to using a language/system without knowing if I will be able to port it to different environments (this means OPERATING SYSTEMS like UNIX). I want to know if (besides A-Ts RapidFIle)( FORTH has been used for a project like this and what the programmers' ex- periences were. Can more of this be discussed here? Finally, I am concerned that most FORTH programmers have a prejudice against people with college degrees ;-). Hadil G.

The source was about 40-50 screens, and implemented about 50 LISP functions. I later rewrote it for the Suns, and it takes about 60K of source code (including many comments). It ran fairly fast, at the same order of magnatude as the native lisp (written in C). It also compiled in less than 1 minute on a loaded SUN-3. Later on in the project I changed directions on it and started to develop a hybrid language--forth with lisp features. I finally had to stop research because I couldn't afford the disk space to store it. (my full development environment approached 400k). What I really liked about the Forth approach was that it was really easy to change the modular parts of the code (like the address space). I also liked how the top level of the code was simple and fairly obvious in control flow (unlike lisps written in C). I also liked the simplicity of adding functions to the core system. Here is a sample (from old memory): \ adds the two arguments in the list that is passed. Returns a number atom. : lisp-add ( args -- sum) lis>2args \ checks for, and converts the list into two items atom># swap atom># \ converts the two atoms to FORTH numbers + \ actually adds them #>atom ; \ changes the number back to a LISP atom \ inserts the LISP function "add", which calls the FORTH function "lisp-add" subr add lisp-add Here is an example of how I could use the above word: ok read ( print ( add 3 7 ) ) eval \ reads the list, then eval's it 10 ...assuming that one has defined the "print" function. Well, this has rambled on long enough. These postings do bring back memories, however. -- Cliff P.S. I once implemented the main core of LISP in LOGO.
