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
+for DOS. You'll have some nice words such as "page"...
- special functions
"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".
+have them reset the definitions at the end of "config.h".
-The second thing to do now is configuring the "Makefile". I know, it's rude,
-but yForth? is drifting on my system for too long, I want to finish it
-within 1996.
-At the moment "Makefile" is ready for GCC (under Linux), it's simple and
-you won't find any problem modifying it.
+The second thing to do now is configuring the "Makefile". At the moment
+"Makefile" is ready for GCC (under Linux), it's simple and you won't find any
+problem modifying it.
Third, type "make all". Yes, that's all.
- yForth? is a "beta" release, I think it has bugs, but, most
important, I'm afraid that some words don't behave as the
standard says they have to.
- - yForth? comes with no warranty, I don't make any warranty about it.
- - yForth? is completely free. You can use, modify, doing anything
- you want with it. If you're going to use it in any project,
- I would be grateful if you cite me, but you're no obliged.
- yForth? is NOT a complete ANS Forth.
- yForth? is written in ANSI C. Ok, you could see some warning while
compiling it, and I've to check it with lint, but it
more if you tell me how fo fix it, but I can't pretend so much, even 'cause
my C is not very readable (few comments...).

+.TH YFORTH 1
+.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.
