Where can I find a Forth for the SUN?
From: w...@ENG.SUN.COM
Subject: Forth for Sun
Message-ID: <910409131...@ucbvax.Berkeley.EDU>
Date: 9 Apr 91 01:11:31 GMT
I know of four Forth's that run on Suns, in increasing order of price:
a) Open Boot PROM - built-in to the SPARCstation PROMs. Inaccessible from
the Unix environment; you have to interrupt the boot process and
then type "n" to get to Forth.
b) TILE - shareware, $50 suggested contribution to Mikael Patel.
Written in C, runs on Suns. Available from the net, but I'm not
sure how to get to it from your site. Maybe somebody else knows.
c) C Forth 83 - $75 from Bradley Forthware. Written in C, runs on
several machines. Tape or floppy.
d) Sun Forth - $200 from Bradley Forthware. Written in metacompiled
Forth/assembler. Unix version of the Forth in the SPARCstation PROMs,
with extensions. Tape or floppy.

Subject: Forth system for MacClassic
Message-ID: <51...@lure.latrobe.edu.au>

I can recommend Mach2 Forth for the Macintosh.
Its strong points are:
1. inexpensive.
2. stable.
3. compiles to machine code so its quick.
4. straightforward access to the Mac toolbox.
5. menu selected templates mean windows and
menus etc. are easy to make for the beginner.
6. standard syntax machine code assembler.
7. the novice programmer does not have to worry
about implementing the Mac event loop.
Weak points are:
1. a rudimentary built in text editor.
2. the Mac event loop is handled by an IO task running
under the multitasker. This makes extensions to
the event loop conceptually difficult.
3. development has ceased but it will be
supported for later Mac System releases.

Forthmacs by Bradley Forthware is also available for the Macintosh.
This is the same Forth that is the basis of Sun's Open Boot firmware.
Macintosh Forthmacs costs $50 for working disk+manual, and $50 extra for
source code.
Forthmacs is available for the following machines:
Atari ST, Macintosh (I and II), OS-9, Sun (680x0 and SPARC), NeXT.

Well I know this ant quite what you want. However, I do know that
MMSForth is still available for the TRS-80. Although written for
NewDos/80 I believe that it works under LS-DOS.
However, Misosys (Roy Soltoff) definitly does do a (cheap) Forth system
for the TRS-80 range (including IBM compatiables) called HartFORTH
(Pro-HartFORTH on the Model IV, HartFORTH'86 for the IBM alikes).

There is a new figFORTH written in C that currently runs under V7 Unix,
Personal C Compiler, and Mix Power C. Porting to other platforms
should be trivial (considering the vast differences of these three
platforms!). That other "C-FORTH" looked pretty primitive by
comparison. From my recollection the author didn't know how to do
defining words, vocabularies, or indirect threaded code. The inner
interpreter is a giant CASE statement! Talk about slow! The file to
look for is HENCE4TH.ARC. It can be found on Genie and
wuarchive.wustl.edu in the /pub directory (it might have been moved to
the msdos/forth area by now). Make sure to get version 1.2, not 1.1. I
can email it to usenet people upon request.
G'luck,
Kevin

From: jpe...@wet.COM (John A. Peters)
Subject: Report on Progrmmable BBS in Forth
Message-ID: <54...@wet.UUCP>
Date: 22 Mar 93 05:48:46 GMT
Q1 How is the "Programmable BBS doing?
It is fine. It has graduated to full time operation as "It is
easier than remembering to turn it on at the right time" says
Levi. He reports that we are getting about one caller a day and
that most of them seem to be first time callers that don't call
back.
Q2 Have there been any suggestions?
There needs to more substance there for the callers.
Q3 What can we do to help?
Help us improve the system, make suggestions, offer help, ask for
a copy of the current system, set it up on your own system and
experiment with improvements, send in the updated system.
Q4 What are you doing to help, John?
I am exploring a BBS that has been mailed to me by it's author,
B0b Lee. It is called B0badell. It is based on the Citadel group
of BBSes. It is a full system that is able to answer the phone,
take a password, record messages and all the usual stuff. The
command !BABY allows the caller to shell out to another BBS
program also provided by B0b called Baby. Baby is a simple
little BBS written in Forth. The advantage of switching to
B0badell from WildCat is that when B0badell runs an application
like Baby, access to DOS is sealed off. We have not published
the passwords that allow the caller to run F-PC based FBBS from
Boyan on the current system because of that risk.
Q5 What is the configuration of the current system?
It is a XT with 40M of hard disk. It is dedicated to the BBS
along with a dedicate phone line. It runs at 1200 and 2400 I
believe. There is a chance of it being upgraded to a 386. The
electricity and phone bills are paid by the Berkeley Fig Chapter
and the operation is handled by Levi from his home in Novato, CA.
Q6 Is it the "Programmable BBS" or is it the "Educational BBS"?
It is the "Programmable BBS", as the goal is to make the source
available to the caller so that any one can work on improving the
system. If there are several versions submitted we will have a
menu of up to about 15 or 16 (Hmmm familiar number) versions with
a method of recording how much time is spent by callers in each
version as well as the callers votes as to their preferences and
their reasons and suggestions.
This will bring up the challenge of group programming. That is,
what is the most workable way to merge several improvements in to
one project when the programmers are not located in the same city
or state? We may need version control software and a utility
that show the differences between two versions of a program.
Q7 Can I try out B0badell
Yes B0badel' home BBS is the Interface BBS at (707) 544-9661
The Programmable BBS is at (415) 892-1543 24 hrs
I am John Peters. I am at (415) 239-5393 Voice
Q8 Will the Programmable BBS carry the Forth Net?
Not right away, as it is not on the critical path between where
we are today and the goal of becoming better than some of all the
other systems. However if we are able to write a Quick packet
version in Forth then why not...

1. FIG-Forth
Here is the source for FIG-Forth published with the original article
(Forth Dimensions, Vol. II, No. 3, pp. 37-40.). The ?PAIRS word was
FIG-Forth's way of implementing a small amount of syntax checking.

BEGIN SP@ CSP @ = 0=
WHILE 2 [COMPILE ENDIF REPEAT
CSP ! ; IMMEDIATE
1a. Here is additional source for FIG-Forth published in Forth
Dimensions, Vol. III, No. 6, pp. 187-188 in an article by Alfred J.
Monroe. He adds a primitive compiled by OF which reduces the amount
of code compiled by OF. Use the definitions of CASE, ENDOF, and
ENDCASE given above.
: (OF) OVER = IF DROP 1 ELSE 0 ENDIF ;
: OF 4 ?PAIRS COMPILE (OF) COMPILE 0BRANCH
HERE 0 , 5 ; IMMEDIATE
Mr. Monroe also gave code for some interesting variants:
: (<OF) OVER > IF DROP 1 ELSE 0 ENDIF ;
: <OF 4 ?PAIRS COMPILE (<OF) COMPILE 0BRANCH
HERE 0 , 5 ; IMMEDIATE
: (>OF) OVER > IF DROP 1 ELSE 0 ENDIF ;
: >OF 4 ?PAIRS COMPILE (>OF) COMPILE 0BRANCH

ENDIF ELSE DROP DROP 0 ENDIF ;
: RNG-OF 4 ?PAIRS COMPILE RANGE COMPILE 0BRANCH
HERE 0 , 5 ; IMMEDIATE
1b. It is quite common to define (OF) as a CODE word and have
it combine the functions of the run-time (OF) and the compile-time
0BRANCH in the previous definitions. This reduces the amount of
compiled code even more.
CODE (OF) ( 1. Remove the top element of the stack and call it A.
2. If A equals the new top element of the stack,
remove the new top element of the stack,
skip over the branch vector, and execute
the code which follows it.
Else
continue execution at the location indicated
by the branch vector.
) END-CODE
: OF 4 ?PAIRS COMPILE (OF) HERE 0 , 5 ; IMMEDIATE
2. dpANS-3
dpANS-3 contains the following definitions (p. 133) to illustrate
control structure extension. Note that it would be quite easy to
optimize OF along the lines suggested above. Note also that there is no
syntax checking. These words may appear anywhere and not necessarily
combined with each other. In fact, ENDOF may be dispensed with entirely
and replaced with ELSE. Compile-time monitoring of the syntax of
control structure words is a perennial Forth problem.

A BRIEF INTRODUCTION TO FORTH
-----------------------------
Forth is both an extensible language and an interactive
program development methodology. Originally developed for
small embedded control mini- and micro-computers, Forth
seems to have been implemented on every major processor
manufactured. It has been used in a wide variety of
applications, including spreadsheets, expert systems, and
multi-user databases.
TWO-STACK ABSTRACT MACHINE
At the most superficial level, Forth is a directly
executable language for a stack-based abstract machine. In
its essential form, the Forth abstract machine has a program
counter, memory, ALU, data evaluation pushdown stack, and
subroutine return address pushdown stack.
Data evaluation in Forth is accomplished on the Data
Stack using Reverse Polish Notation (RPN), also called
postfix notation. For example, the following sequence typed
from the keyboard:
3 4 + 5 * . __35 ok__
interactively pushes the value 3 on the stack, pushes the
value 4 on top of the 3, destructively adds 3 and 4 to get
7, then multiplies by 5. The . operation displays the
single resultant top value on the stack, 35 (computer output
is underlined). "ok" is the Forth command prompt.
Operations such as SWAP and DUP (duplicate) reorder and
replicate the top few Data Stack elements.
FACTORING
At a deeper level, Forth programs use RPN not as an end
in itself, but rather as a means to achieve simple syntax
and flexible modularity. Small, simple programs to perform
complex functions are written by reusing common code
sequences through a programming practice known as factoring.
Subroutine calls and returns are an important part of
Forth programs and the factoring process. As an example,
consider the following function (called a word in Forth)
which computes the sum of squares of two integers on top of
the Data Stack and returns the result on the Data Stack:
: SUM-OF-SQUARES ( a b -- c ) DUP * SWAP DUP * + ;
The Data Stack inputs to the word at run-time are two
integers a and b. The Data Stack output is a single integer
c. The : denotes a function definition with the name SUM-
OF-SQUARES. The ; terminates the definition. Comments are
enclosed in parentheses. This example follows the Forth
convention of including a stack-effect comment showing that
a (the second stack element) and b (the top stack element)
are consumed as stack inputs, with c produced as the stack
output.
By the process of factoring, the example program would
be re-written in Forth using a new definition (a factor)
called SQUARED to allow sharing the common function of
duplicating and multiplying a number on the Data Stack. The
separation of the Return Stack from the Data Stack in the
abstract machine allows the values on the Data Stack to be
cleanly passed down through multiple levels of subroutine
calls without run-time overhead. In this new version, Data
Stack elements are implicitly passed as parameters from SUM-
OF-SQUARES to SQUARED:

Good Forth programmers strive to write programs
containing very short (often one-line), well-named word
definitions and reused factored code segments. The ability
to pick just the right name for a word is a prized talent.
Factoring is so important that it is common for a Forth
program to have more subroutine calls than stack operations.
Factoring also simplifies speed optimization via replacing
commonly used factors with assembly language definitions.
In the preceding example, SQUARED could be re-written in
assembly language for speed while maintaining the same stack
effects.
Writing a Forth program is equivalent to extending the
language to include all functions needed to implement an
application. Therefore, programming in Forth may be thought
of as creating an application-specific language extension.
This paradigm, when coupled with a very quick
edit/compile/test cycle, seems to significantly increase
productivity. As each Forth word is written, it can be
tested from the keyboard for immediate programmer feedback.
For example, the definitions above could be summarily tested
with:
3 SQUARED . __9 ok__
3 4 SUM-OF-SQUARES . __25 ok__
INTERPRETATION, COMPILATION AND EXECUTION
Forth systems use two levels of interpretation: a text
interpreter and an address interpreter. When accepting
keyboard or file-based input, the text interpreter extracts
whitespace-separated character strings. In interpretation
mode it attempts to execute the corresponding words (numeric
input is trapped and converted as a special case). : is a
word like any other, but creates a new dictionary entry
containing the word name (symbol) and places the text
interpreter into compilation mode. While in compilation
mode, most words extracted from the input stream are
compiled to a pointer to the word's definition in the
dictionary instead of being executed.
A compiled Forth program is a collection of words, each
of which contains a statically allocated list of pointers to
other words. Ultimately the pointers lead to assembly
language primitives, some of which are typically user-
written. The Forth address interpreter is used to execute
compiled words, classically using threaded code techniques.
The Forth text interpreter, while not used in executing
compiled programs, is often included in applications as the
basis of a command-line user interface.
Forth systems use one-pass compilation. There is no
explicit Forth parser (and, for practical purposes, no
formal grammar). Control flow words have a special
immediate attribute, and are executed immediately even when
the text interpreter is in compilation mode. Immediate
words, when executed, typically cause compilation of special
structures. For example, IF compiles a branch conditional
upon the top runtime Data Stack value, and the matching THEN
(the "endif" word) back-patches the branch target address.
Users can readily create their own immediate words, thus
extending the compiler by adding new control flow structures
or other language features.
Data structures are created by another special class of
words: defining words. Defining words have two parts: the
CREATE clause creates the dictionary entry for the data
structure instance, while the DOES> clause is a definition
shared by all data structures created by that defining word.
For example, an array defining word creates a named array
and reserves storage with its CREATE clause, and computes an
address (given indices) in its DOES> clause. Defining words
are commonly used to hide data structure implementations and
to create families of similar words.
Forth programmers traditionally value complete
understanding and control over the machine and their
programming environment. Therefore, what Forth compilers
don't do reveals something about the language and its use.
Type checking, macro preprocessing, common subexpression
elimination, and other traditional compiler services are
feasible, but not included in production Forth compilers.
This simplicity allows Forth development systems to be small
enough to fit in the on-chip ROM of an 8-bit
microcontroller. On the other hand, Forth's extensibility
allows "full-featured" systems to consume over 100K bytes
and provide comprehensive window-based programming
environments. Forth also allows (and often encourages)
programmers to completely understand the entire compiler and
run-time system. Forth supports extremely flexible and
productive application development while making ultimate
control of both the language and hardware easily attainable.

FAQ account for comp.lang.forth
What is this dpANS and what happened to BASIS?
dpANS is a draft proposed Ansi National Standard. The BASIS documents
were the internal working documents of the Forth Technical Committee
X3.J14. Prior to this, to my knowlege, the internal working documents
of any ANSI Technical Committees were not released to the public.
X3.J14 broke new ground by not only making those documents available,
but by making them available electronicly. X3.J14 has now made the
Forth dpANS available for public review. While the first two dpANS
documents were only available in print form, the 3rd is now available
electronicly. See below for more info on dpANS 3.
How can I send email to the ANS Forth Technical Committee?
You can also submit comments electronicly:
For those of you worried about mail getting thru to ANSI by Feb. 25,
I'm happy to report that it is possible to EMAIL public review
responses. X3 has a new CompuServ account. From whatever board you're
on, it's presumably possible to address CompuServ; having figured out
how to do that, address your mail to:
Lynn Barra, X3, c/o Dan Arnold, 75300,2354
If there's not enuf address space to list both names, just use Dan &

X3 Announces the Third Public Review and Comment Period on
X3.215:199x, Programming Language FORTH
Washington, D.C. -- Accredited Standards Committee X3, Information
Processing Systems announces the two-month public review of
X3.215-199x, Programming Language FORTH. The comment period
extends from April 2, 1993 through June 1, 1993.
The purpose of this standard is to promote portability of Forth
programs for use on a variety of computing systems, to facilitate
communication of programs, programming techniques, and ideas among
Forth programmers, and to serve as a basis for future evolution of
the Forth language. The standard specifies the forms that a
program written in the Forth language may take and the rules for
interpreting the meaning of a program and its data.
This third public review is being issued due to technical changes
in the draft standard as a result of comments received during the
second pubic review.
On an experimental basis, an electronic public review of
X3.215:199x is also being conducted using Internet and CompuServe.
The dpANS is accessible in each environment, and the review is
supported by an Internet mail group. In addition, for the first
time X3 is permitting the electronic submission of public review
comments as a part of this experiment.
To obtain the dpANS using CompuServe you must first be a member of
OASIS which can be done by contacting Dan Arnold at (202) 626-5738
to receive a sign-up kit. Once you are a member, you should type
GO XCB. The file is located in the X3 Bulletin Board in the X3J14
dpANS Library.
On Internet, use anonymous FTP with host playground.sun.com to
obtain the file/pub/incoming/READMEd5.txt which defines procedures
that must be used during this review period. If you are unable to
get this file, send an e-mail to ansforth...@minerva.com,
notifying the TC of your problem. The ReadMe file will be sent to
you.
Please note the electronic public review and the corresponding
procedures are experimental. Comments on this process are also
welcome.
The comment period ends on June 1, 1993. Please send all comments

The question often arises: where can I get "foo" via anonymous FTP (FTP
is the Internet File Transfer Protocol)?
There is a nice database listing Internet archives; you can access it via
Telnet. Here's how:
telnet quiche.cs.mcgill.ca

(Lots of introductory messages; use "help" to learn more)
archie> prog forth
The "prog forth" query lists over 100 Forth things available on various
FTP sites. I searched the listing for "atari", and found 2 places where
Forthmacs is available:
watserv1.waterloo.edu /micro/atari-st/forthmac.arc
terminator.cc.umich.edu /atari/languages/forth.arc
Obviously, you can look for other things besides Forth; I have used archie

You can find them on SIMTEL20 (WSMR-SIMTEL20.ARMY.MIL) and in the
SIMTEL20 mirror on wuarchive.wustl.edu. Because the exact file names
often contain version numbers, I'm not including the file names
here, only the directory names. Check out 00-index.txt in the
directories for specific info and what file is what. On SIMTEL-20,
look in directories:

On wuarchive, look in directories:
/mirrors/unix-c/arc-progs
/mirrors/unix-c/file-mgmt
If you have email only access, please see the other regularly
posted message for how to access FTP archives via email.
You might also try using the archie server to find other sites
that have these programs. (See previous question).

The annual Working Group on Forth Education was held at the 1991 Rochester
Forth Conference. As chairman of the group, I pointed out that apart from
some activity resulting from the 1990 Working Group, notably on the part
of Jack Brown of BCIT, there was very little carry over from one year to
the next. So, I volunteered to start and administer a Forth Education List
on Internet. I have now decided to publish an electronic newsletter--more
or less regularly--and this is it!
This issue is being sent to some of the people who attended the 1991 FEWG,
namely, those who gave me their electronic addresses. You can subscribe to
the list by sending an e-mail request to

Contributions to the newsletter can be sent (for editing) to
Submissions to the list can be sent to

Topics for both types of submissions that have been suggested at the WG
include
* Forth textbooks
* Educational Forth boards
* Forth teaching resources
* Teaching the ANSI Standard Version of Forth
* How to increase programming productivity through education
* Boot Prom educational materials
* anything else impinging on education and Forth

FAQ account for comp.lang.forth
What Forth libraries are available, and how can I access them?
There are several repositories of Forth programs, sources, executables,
and so on. These various repositories are NOT indentical copies of the
same things. Material is available on an AS-IS basis due to the charity
of the people involved in maintaining the libraries. In addition to the
sources listed below, many of the ForthNet branches also have libraries
available. See FAQ Part 10 for information on accessing ForthNet.
Getting Forth files directly from The Forth Interest Group:
The Forth Interest Group maintains a library of Forth files available on
disk. You can write them for an order form, their address is in
FAQ Part 02. They also have a very extensive library on line on GEnie.
For GEnie access information, see FAQ Part 10.
Getting Forth files via FTP:
There is an FTP site in Portugal devoted to Forth, which contains a
mirror of the FIG library on GEnie, plus whatever anyone has donated.
The archive is run by Paulo A. D. Ferreira who has donated the resources
for it. The archive machine name/address is:
asterix.inescn.pt 192.35.246.17
and the files are in the directory:
pub/forth
Please note: There are several other FTP sites on the network that
have Forth directories. However, this is the only FTP site
that has a respository specificly for Forth files of any
and all kinds. SIMTEL20 has some MSDOS only files, but
those are very old. A few other sites are the primary
distribution points for particular Forth systems. If you
are the maintainer of such a site, please email me some text
that I can add to the FAQ messages.
Here is a copy of the pub/forth/README file.
*Especially note the time restriction for accessing the archive.*

FAQ account for comp.lang.forth
What is ForthNet?
ForthNet is a virtual Forth network that links designated message bases
of several Bulletin Boards and Information Services in an attempt to
provide greater distribution of Forth related information.
ForthNet is provided through the courtesy of the SysOps of its various
links who shunt appropriate messages in a manual or semi-manual manner.
An incomplete list of the branches of ForthNet includes:
UseNet's comp.lang.forth
BitNet's FIGI-L
the BBoard systems RCFB, ACFB, LMI BBS, Interface BBS, Grapevine
FIG's RoundTable on GEnie.
What are the restrictions and guidelines for ForthNet messages?
The various branches of ForthNet do not have the same rules of
appropriate postings or ettiquette. Many BBoard posts are very chatty
and contain some personal information, and some also contain blatant
commercial advertising. Most comp.lang.forth posts are not like that.
Because ForthNet messages are routed beyound the system from which they
originate, we, the manual and semi-manual linkers of ForthNet, ask that
you try to keep the lines in your messages to under 77 characters in
length. You do not have to do that. If you do use long lines, be aware
that your message will end up formatted differently on the various
branches of ForthNet.
How do I send email to some one who has posted a message on ForthNet?
There is NO e-mail link between the various branches of ForthNet. If you
need to get a message through to someone on another branch, please either
make your message general enough to be of interest to the whole net, or
contact said person by phone, USMail, or some other means. Thoughtful
message authors place *a few* lines at the end of their messages
describing how to contact them (electronicly or otherwise).
How do I access ForthNet?
From UseNet: comp.lang.forth
ForthNet messages that are ported into comp.lang.forth from the rest of
the ForthNet all originate on GEnie. All such messages are ported into
comp.lang.forth with a from line of the form:
