as they are derived from code fragments for which no author information

electronic mail addresses listed on the 'Credits' page, or by
mailing a disk containing a description of the problem and the
necessary software and files to the Procyon address.

\section{User Projects}
If you're working on a project which
utilizes GNO/ME in some way, we'd like to know about it. Just
contact us by mail, phone, or whatever is most convenient for
you, and tell us about your project. If possible, we'll
coordinate your efforts with those of other programmers. If we
really like your project and think it may be useful to others, we
may include it on the next GNO/ME distribution!
\section{Software Piracy}
If you have illegally copied computer software from someone
and are now reading this, take a moment to reflect on what you've done.
Many computer software applications are huge projects, consuming
many man-years of effort, huge amounts of money, and a lot of grief on the
part of the developers.
For example, the Byte Works' ORCA languages and development
environment (as of November 1997) consists of over 220,000 lines
of source code, \em not \rm including the libraries, tool
interface files, test programs, samples, or the 5 800k disks
of source in the courses for each language. This work represents
approximately 17 man-years of development, support, marketing,
and management.
Is it right that you're now benefiting from
developers' efforts without any just compensation to the authors?
Many programmers are born, bred, and raised in the spirit of
computing. They love to write software, and probably always
will. But if they cannot make enough money to make it
worthwhile to continue their work, then they won't; because by
worthwhile, we mean not only food on the table, but resources for
expansion and continued growth. In short,
support them and they'll support you.
Computer software is very inexpensive when you
consider what it allows you to do.
To all you who properly pay for the software you use:

\chapter{The GNO/ME Package}
\section{The GNO/ME Package}
GNO is a large and complex system. There are many pieces to it;
too many to list in detail here. However in general, the documentation
consists of the following parts. All of these are available
at the \gnodocs{GNO Documentation Page} and via anonymous ftp from
\tt trenco.myrias.com\rm:
Included in your GNO/ME Version 2.0 package are:
\begin{itemize}
\item This GNO/ME overview.
\item The GNO Shell User's Manual.
\item The GNO Kernel Reference Manual.
\item A selection of utility and library documentation.
\item A reading list containing a wide selection of books
for both the user and the programmer
\item Three disks containing the GNO Kernel, GNO Shell, and
loads of utilities.
\item GNO Overview and Installation Manual.
\item GNO Shell User's Manual.
\item GNO Kernel Reference Manual.
\item Online Manual Pages.
\item GNO Frequently Asked Questions (and Answers) List
\end{itemize}
\chapter{Hardware Requirements}
The base distribution of GNO itself is also available via anonymous
ftp from the same site. It comes as a three-disk set which makes
up GNO v2.0.1. There is a single disk for each of the upgrades
to versions 2.0.2, 2.0.3, and 2.0.4. There is also a custom version
of ORCALib that should be installed if you are using ORCA/C v2.0.x
with GNO v2.0.4.
Finally, there is an extensive collection of third-party GNO utilities
available. A listing of these utilities may be found at
\hturl{http://www.arrowweb.com/sbehrens/describe.htm}
or
\hturl{http://www.servtech.com/public/phoenix/computers/gno/index.html}.

\section{Obtaining Assistance}
Since GNO was reclassified as freeware in the fall of 1997,
Procyon no longer provides direct support to users, other than those
that had paid the full price for GNO prior to the reclassification.
There is, however, a group of programmers and users of GNO who are
able to render assistance on a volunteer basis. Some of these programmers
are also actively involved in upgrading the base GNO distribution.
If you require assistance, the following two methods of contact are
preferred:
\begin{itemize}
\item
Post a message to the USENET news group, \bf comp.sys.apple2.gno\rm.
Remember that messages usually take at least a few hours to propagate
around the world. Answers also take time to propagate.
\item
Ask a question on the Delphi Apple II Programmers' Forum. There
are subject areas set up for GNO under ``third party technical support''.
Delphi is accessible via \hturl{http://delphi.com}. (Delphi is
recommended for discussion of programming topics in general and
has, for the most part, taken over from Genie as the centre of
online Apple II communication. Some packages are available free of
charge. Visit Delphi for more details.)
\end{itemize}
As a last resort, you can contact Devin Reade (one of the GNO
development team) at \htmailto{gdr@eddore.myrias.com}. Please don't
use this method unless absolutely necessary, as Devin is not always
available. More importantly, asking questions in an open forum
provides for peer review; if an answer is wrong, it can be corrected
by other developers.
Finally, for those who paid for GNO before it was reclassified,
Jawaid can still be contacted at

\item Learning UNIX \cite{gardner}
\item The UNIX Operating System \cite{christian}
\item Peter Norton's Guide to UNIX \cite{norton}
\item UNIX in a Nutshell \cite{gilly}
\item Life with UNIX --- A Guide for Everyone \cite{libes}
\item UNIX for the Impatient \cite{abrahams}
\item Learning the vi Editor \cite{lamb}
\end{itemize}
The following are recommended readings for programmers:
\begin{itemize}
\item The Design and Implementation of the 4.3 BSD UNIX Operating System \cite{leffler}
\item The UNIX Programming Environment \cite{kern_pike}
\item Advanced Programming in The UNIX Environment \cite{stevens}
\item Advanced UNIX Programming \cite{rochkind}
\item Using C on the UNIX System \cite{curry}
\item POSIX 1003.1 \cite{posix1}. This would normally be considered
required reading except that the POSIX standards (like most
standards) are very expensive. If you can obtain a copy, you
should try to do so.
\end{itemize}
The following should be considered as required readings for programmers:
\begin{itemize}
\item The ANSI X3.159-1989 (ANSI/C) Standard \cite{ansic}. This, however,
is an expensive manual and beyond the financial reach of many
hobby programmers. A low-cost alternative is Schildt's

\section{Freeware Status}
The following message was distributed by Jawaid Bazyar by email and
by USENET news, in the fall of 1997:
\begin{quote}
As the man behind Procyon Enterpsises Inc., a long-time Apple IIGS
developer and one of the last commercial developers for the platform,
I regret to announce the end to sales of my first product, the GNO
Multitasking Environment (GNO/ME).
With my last distributor, EGO Systems, closing its doors, I cannot
justify the time and expense of continuing to produce the software. I
also didn't feel it was fair to the customers to continue to charge them
for the product, when I would be unable to support them in the manner
I would like, due to my intense involvement in my new ISP business.
However, instead of simply stopping sales of GNO and letting the software
wander into oblivion, I am placing GNO into ``freeware'' status, and I am
also making available all source code to the 2.0.4 version to the public
and the development community.
I will still sell printed manuals to anyone who wants one, for \$20 or
so, but this is just to cover printing and shipping costs. Purchasing
a manual will not entitle the buyer to support from me of GNO/ME.
Anyone who paid the normal \$89 price to EGO Systems (or to me directly)
for GNO will continue to receive support from me, and I will rely partly
on the help of the ``GNO-Devel'' list for assistance in this support.
Speaking of that, the GNO-Devel list is headed by Devin Reade,
and its members are programmers who have the time and devotion to
continuing to develop the GNO system. To their capable hands I leave
the software. The first task of this group is to put together a GNO
distribution based on the latest ORCA/C and ORCA/C libraries. Devin will
post followup info on csa2g and any inquiries should be directed to him
at <gdr@eddore.myrias.com> for the moment.
Thank you all for your support in the past of my company and myself,
and best wishes to you all for the future!

\chapter{Installation for GNO v2.0.4}
\em
\textbf{Important Note:}
This chapter is very out-of-date. It was written for GNO v2.0.1, and
has had only minor updates since that time. It very much needs to
be rewritten (concurrently, of course, with updates to the actual
installation process). However, this is unlikely to occur until
GNO v2.0.6 is released. This chapter does not apply to installing
GNO v2.0.6.
Before attempting to install GNO v2.0.4, you are strongly encouraged to
read this entire chapter, and then consult the
\faqhtml{GNO FAQ} (Frequently Asked Questions list, which is also
available via \faqtext{ftp}) for those sections related to installation.
Suggestions for updating this document (without making major changes
to the GNO v2.0.4 distribution itself) are welcome. Please email
your suggestions to Devin Reade at \htmailto{gdr@eddore.myrias.com}.
\rm
GNO/ME is a very large system. Most of the
system is stored on the three disks in a compressed format. For
this reason we recommend that you read this section carefully and
use the included automated installation program to save yourself
the major headache of arranging everything. You'll need a hard
drive partition with at least 5 Megabytes free to install GNO/ME.
The entire installation process should take no longer than 10
minutes.
If you are upgrading from GNO 1.0 to GNO
2.0, we recommend that you install GNO 2.0 on a new area of your
hard drive. This is because GNO 2.0 provides new versions of
almost all the utilities and other software provided with GNO
1.0. You can then move the parts of your old system that aren't a
part of the standard GNO 2.0 distribution over to the new
installation.
The installer program is able to the copy
the GNO libraries for use with the ORCA languages and tools. If
you want to use your ORCA languages and tools, you should answer
the appropriate questions during the install process. ORCA
installation is covered in more detail below.
\section{Installing GNO v2.0.1}
\begin{description}
\item[Step 1]
Copy the contents of \texttt{/GNO.Disk1} to the partition where you want
to install GNO/ME. The easiest way to do this is to run the IIGS
Finder, insert the \texttt{/GNO.Disk1} disk, and drag the
\texttt{/GNO.Disk1} icon onto the icon of the drive you want to install on.
The Finder will tell you that the disks are of a different size, and
ask you if you wish to place the contents of \texttt{/GNO.Disk1}
in a folder on the hard drive partition.
Answer ``Yes'', and the Finder will copy the data.
\item[Step 2]
Open the newly created \texttt{GNO.Disk1} folder on the partition
and execute ``Kern'' by double-clicking on the \texttt{Kern} icon.
\texttt{GNO.Disk1} contains a minimal GNO system which you have
just started up. You'll see some copyright messages, and after a few
seconds the desktop will appear.
\item[Step 3]
Install will ask you questions before the installation process begins.
Questions asked by Install are boldfaced in this section.
If you're uncertain of how to answer, click on the ``Info'' button
to get more information on the question. This information is
reproduced here for ease of reference.
\begin{description}
\item[Do you have existing Byte Works (ORCA) language products?]
If you use Byteworks language products such as ORCA/C, ORCA/M,
ORCA/Pascal, and so forth and wish to use them from GNO/ME then
answer ``Yes'' to this question. Otherwise, answer ``No''.
Clicking on the ``Info'' button will display the following text:
\begin{quote}
If you currently use products such as ORCA/C, ORCA/Pascal,
ORCA/M, etc., and wish to use them from GNO/ME then you should
answer ``Yes'' to this dialog.
Install will then ask you to locate the file ``ORCA.SYS16'' (the
ORCA Shell). Usually, it will be in a directory called ``ORCA'' on
one of your hard drive partitions. On our system, it is
\texttt{:software:orca}.
The location of this file determines where Install puts the
GNO-specific ORCA/C header files and libraries (in the ORCA
LIBRARIES directory). If you have renamed ORCA.SYS16 to
something else, select that instead.
Install uses this information to correctly set the ORCA prefixes
and add the EXECUTABLES directory to the \$PATH variable in your
gshrc file. See the GNO Shell User's Manual, Appendix B, for
more information on the ORCA prefixes.
\end{quote}
\item[Do you want to install the modified ORCA/C 2.0 ORCALIB library?]
If you have ORCA/C 2.0 installed and you answered ``Yes'' to the
previous question, then you should answer 'Yes' now.
If you have ORCA/C 1.3 installed, or you do not have any ORCA languages or
tools, then you should answer ``No''.
Clicking ``Info'' will display the following text:
\begin{quote}
GNO/ME 2.0 comes with a modified version of the ORCA/C ORCALIB
standard library. This library adds specific support for some of
GNO's special files (pipes, terminals, etc) transparently
and corrects other problems the standard ORCALIB has with
GNO.
This special ORCALIB is only for use with ORCA/C 2.0. It will
NOT work with previous versions of ORCA/C.
Note that all of GNO's other libraries (libgno, libbsd, libc)
work fine with ORCA/C 1.3.

\item[Do you want to install the Multi-User package?]
If you wish to have the Multi-User package installed, answer ``Yes''.
It is recommended that new users do not install this package until they are
familiar with the system. This package is not fully discussed in the
GNO/ME manuals and may introduce many unfamiliar concepts.
Clicking ``Info'' will display the following text:
\begin{quote}
The ``Multi-User'' package consists of a number of
cooperating programs, including \bf init\rm(8) and \bf login\rm(8).
MU provides for password-protected access to the GNO Shell via the
console or serial ports (modems and dedicated terminals).
It also handles multiple user accounts, and a certain
level of protection between users.
If you will be using a terminal with GNO, or want to be able to dial
into GNO with a modem, you should install MU.
You may wish to hold off setting up the Multi-User package until you
learn your way around GNO a little better, as it's simple
to set up MU later.

\item[Step 4]
The Installer will now proceed to arrange the GNO Multitasking
Environment on your hard drive. Initially, the contents of
\texttt{/GNO.Disk1} will be moved into the proper places on the
volume you have chosen. When asked by the Installer, you should place
\texttt{/GNO.Disk2} and \texttt{/GNO.Disk3} into the disk drive. The
contents of these disks will be extracted and decompressed into their
proper places.
\em
If the installer cannot finish it's tasks for some reason, it will
abort to the shell. At this point you should study the error messages
to determine the cause of the failure,
\rm
\item[Step 5]
When the Installer finishes, you will be returned to the GNO prompt.
At this time you should type ``exit'' to return to Finder and delete
the \texttt{GNO.Disk1} directory, as it is no longer needed (GNO
is completely installed in a subdirectory ``\texttt{GNO}'' on the
same partition \texttt{GNO.Disk1} is on.

\section{Installing GNO v2.0.2 Through v2.0.4}
GNO versions 2.0.2 through 2.0.4 were distributed as sequential
updates to version 2.0.1, rather than as complete distributions.
Consequently, you should install each of the version 2.0.2,
2.0.3, and 2.0.4 distributions, \em in sequence, \rm over top of your
version 2.0.1 distribution.
You should also obtain and install the Multi-User Update.
\section{What Has Been Installed?}
\em
\textbf{Note:} This list of directories is somewhat out of date.
You should consult the \faqhtml{GNO FAQ} (also available via
\faqtext{ftp}) for more current information.
This section will be updated, but likely only after GNO v2.0.6 is
released.
\rm
If you examine the directory that you chose
for GNO/ME, you will find that the Installer has created several
directories. Here is a brief rundown of thier contents:
\begin{rawhtml}
<!-- cleantable-start -->
\end{rawhtml}
\begin{tabular}{ll}
\bf :gno:bin: \rm &

includes serial drivers for the IIgs' built-in modem and
printer ports.
\end{minipage} \hfill \\
\bf :gno:etc: \rm &
\begin{minipage}[t]{8cm}
Various system configuration files
\end{minipage} \hfill \\
\bf :gno:initrc \rm &
\begin{minipage}[t]{8cm}
This a startup file for kern and must remain in this directory.
\end{minipage} \hfill \\
\bf :gno:kern \rm &
\begin{minipage}[t]{8cm}
This is the GNO kernel. Launch this to start GNO/ME.
\end{minipage} \hfill \\
\bf :gno:lib: \rm &
\begin{minipage}[t]{8cm}
This directory is provided for programming libraries that are
used only occasionally. Various applications may also keep
auxilliary files here. It is currently empty.
\end{minipage} \hfill \\
\bf :gno:tmp: \rm &
\begin{minipage}[t]{8cm}
This directory is used by various utilities as location for
their temporary files. It is currently empty, and should
be cleaned on periodically.
\end{minipage} \hfill \\
\bf :gno:user: \rm &
\begin{minipage}[t]{8cm}
This directory is created if you installed the Multi-User package.
It contains a user directories for users of the system.
Currently there is only one: ``root''.
\end{minipage} \hfill \\

\chapter{Desk Accessories}
The following is a description of the desk
accessories that are shipped with GNO/ME.
\section{GSI NDA}
The \textit{Graphical Shell Interface New Desk Accessory}
allows you to access the shell from a window inside a
desktop application. Selecting ``GSI'' from the Apple menu opens a
window and brings up a shell in it. You can use the shell in this
window just as you would in text mode.
At this time, GSI doesn't support any
terminal emulations --- it's a ``dumb'' interface. As a result,
full screen programs like \bf less\rm(1) and \bf vi\rm(1) will not
work properly in GSI.
\section{Suspend NDA}
The Suspend New Desk Accessory allows you
to temporarily stop a desktop program and return to the text
shell. To return to the desktop program, simply type the foreground
command, ``\texttt{fg}''.
You may put desktop programs in the background
(through the ``\texttt{bg}'' command)
at your own risk. This is not guaranteed to work for all programs,
and putting a desktop program in the background will not put the
Apple IIgs in text mode.
Also, do not run another desktop program
when one is currently suspended. The GNO kernel tries to cleanly
terminate the second program, but may not always be able to
accomplish this.
\section{GNO Snooper CDA}
The GNO Snooper CDA is a utility that is
very helpful in debugging software, and reporting system crashes.
Snooper has access to information inside the kernel that is not
generally available to processes.
When you enter the control panel and choose
``GNO Snooper'' a process list is displayed, which is
very similar to the \bf ps\rm(1) shell command, and a menu is presented
with the following options, each of which is invoked by typing it's
first letter:
\begin{description}
\item[D)etails]
Get detailed information on a process.
Snooper asks you for the process ID number of the process you
want to investigate. Snooper then dumps the state of the 65816
registers and shows various other information about the process.
\item[K)ill]
This option sends a SIGKILL to a process. Just type in the process ID
of the process you want to kill.
\item[P)rocess Group Dump]
Dumps the system process group tables,
which is very useful for debugging code which manipulates process
groups. The first table, ``pgrp'', is the process group reference
count table. This table lists how many processes (and TTYs)
belong to that process group.
Process group ids start at 2, so the first pgrp listed is 2.
The second listing is the ttyStruct table.
This table shows to which process group each TTY belongs. The TTYs start
with .null (0), then move on to .ttyb, .ttya, .ttyco, etc.
\item[F)ile Table Dump]
Lists all open files known to GNO.
The information is presented in tuples. The first element is the
real GS/OS refNum or device driver ID. The second is the type of
file (GSOS, ttyXX, or PIPE). The third is how many references to
that file are open. This information is global, so if two
processes have .NULL opened, the refcount for .tty00 will be 2.
