+yForth? v0.1+beta - READ THIS (AND ONLY THIS) TO GET yForth? RUNNING.
0) Hello world!
Here's a little file which will help you having yForth? running in few
together in the file "udio.c". If you're using Turbo C, Borland C, or any
compiler which supplies the "conio.h", you can define HAVE_CONIO in
your "config.h" file and go.
-Note that even if in file "udio.c" you'll see some lines telling you:
-#ifdef HAVE_CURSES
-or similar, yForth? actually doesn't support CURSES library. I've decided to
-stop my work as soon as something machine depended that was too messy has
-came around.
2) Where does the name yForth? came from?
I've been charmed by Forth since the first time I "played" with it, but
Below data definition you'll have to change the maximum values of your
system. See "limits.h".
- terminal
-Finally, define HAVE_CONIO if you're using Turbo C, Borland C or GCC for DOS.
-You'll have some nice words such as "page"...
+Finally, define HAVE_CONIO to 1 if you're using Turbo C, Borland C or GCC

"asinh", "acosh", "atanh" aren't provided by all the libraries, if you don't
-have them delete the definitions at the end of "config.h".

-The second thing to do now is configuring the "Makefile". I know, it's rude,

-At the moment "Makefile" is ready for GCC (under Linux), it's simple and

+yforth for DEBIAN
+----------------------
+
+This is a small implementation of the better part of the ANS Forth core
+standard. It is less appropriate for hacking Forth scripts under Linux than,
+say, gforth... but it has great promise, and I'm sufficiently interested in
+playing with it for embedded environments that I've decided to go ahead and
+package it.
+
+The author says it's "freeware", and you can do anything you want with it,
+unencumbered even by the GPL. Enjoy.

+Description: A small freeware Forth environment in ANSI C
+ yForth? is an interestingly small implementation of Forth for Linux. It
+ suffers several deficiencies. For general Forth programming or learning
+ under Linux, yForth? is not the best choice.
+ .
+ From the author's README:
+ .
+ yForth? is a Forth environment written entirely in ANSI C, making it
+ extremely portable. The first thing I want to tell you about yForth? is
+ that it seems a joke compared to other systems such as gForth or PFE.
+ .
+ Nevertheless, you could find yForth? nice, in which case you're invited to
+ explore yForth?
+ .
+ It's yours, you can make anything you want with it. If you want an explanation
+ of the words provided by yForth? please refer to the draft of ANS Forth or
+ something equivalent. The Net will help you.
+ .
+ Do not expect the prompt "ok" to come up when you run yForth?, the standard
+ says that "ok" shall be printed AFTER every successful command execution...

+.SH NAME
+yforth \- a small, free Forth implementation
+.SH SYNOPSIS
+.B yforth
+.SH DESCRIPTION
+This is a small implementation of the Forth programming language, somewhat
+easier to read than larger Forth implementations like Gforth.
+
+It is not being actively developed or maintained. If you find it useful,
+great. If not, don't expect much help. The www.forth.org site is a good
+place to get more general information on Forth.
+
+Serious Forth authors would be advised to use Gforth instead of this package.
+
+.SH AUTHOR
+This man page was cobbled up for the Debian distribution by Bdale Garbee.
