Could someone give me som information about Forth's for the Amiga.
I heard JForth is available, but I have no information about it.
1. Is it native 16/32-bit?
2. Does it compile to machinecode?
3. Does it have access to ALL amiga libraries?
4. What is included?
5. Anything else of value?
6. $$$?
I know forth so you don't have to tell me how hard it is. It isn't.
Anybody know anything ? Please inform me.
ALSO:
Is there a Prolog compiler/interpreter with access to amiga libraries that
will run in 1 Meg ?.
Tnx

I've been using the public domain midi.library quite a bit from JForth lately. > 4. What is included? Assembler, of course. Also, disassembler, C-structure support, include file conversion (.h to .j), object-oriented development environment and a very large number of useful tools that support graphics, Intuition, file I/O, IFF and a zillion other things. JForth does not use the traditional "screen" file system, though there's a sub-system provided for that, too, if you want it. Instead, it uses the Amiga's own native file system, like any other application. Compose in your favorite text editor, and load into JForth by filename. > 5. Anything else of value? Yes. JForth v2.0 ("JForth Professional") is about to be released. I've been beta-ing it. Probably the most important feature of this new version is CLONE, a target compiler. A programmer who wants to compile a JForth application passes CLONE the name of the word which serves as the application's entry point. CLONE then rips down through the dictionary, extracting code called by the application and removing dictionary headers to produce a stand-alone executable image, with command line parsing, of course. "hello world" compiles into about 2800 bytes. Another important feature is the "module", a construct which allows large chunks of forth code to be linked into (and unlinked from) the interpreter's search path without taking up dictionary space. Amiga 'includes' and the assembler are two such modules. > 6. $$$? About $90US for the current version, $150 for JForth 2.0, I think. >Is there a Prolog compiler/interpreter with access to amiga libraries that >will run in 1 Meg ?. Sorry, don't know about Prolog. disclaimer: I'm not affiliated the Delta Research (makers of JForth), except as a very satisfied customer and unpaid beta-tester. Peter M.

There is a PD Prolog on two consecutive fish disks. It runs in 1meg. However, I do not know if it has access to the Amiga libraries. tozz@hpindda.hp.com
