FontGDOS Release - May 28, 1992
Legal Statement:
FONTGDOS.PRG and its associated Drivers, Control Panel Extensions, Desk
Accessories, and Installation Program ("FontGDOS") are Copyright
1989-1992 Atari Corporation. FontGDOS may not be uploaded to any
bulletin board systems, included in any PD or user group libraries,
sold, or distributed in any way without the express written approval
of Atari Corp.
In no event will Atari Corp. be liable to you for any incidental
damages of any kind, including loss of profits or data, even if Atari
Corp. is aware of the possibility of such damages arising from the
use of this software.
Atari is pleased to release FontGDOS, the latest version of the
Graphic Device Operating System for Atari TOS-based computers.
FontGDOS is a direct replacement for all existing versions of
GDOS.PRG. It provides many benefits over the existing version of
GDOS, as well as the "GDOS-clones" that are on the market:
1) Bitmap Caching for more efficient use of RAM; fonts are loaded
into RAM on an as-needed basis instead of being resident constantly.
2) GEM/3 Bezier Curve VDI routines become instantly available to
correctly written GEM applications.
3) More printer drivers are available than ever before, including
Deskjet, Paintjet, Okidata Color, Epson Compatible 24-pin BW and
Color.
4) Desk Accessories or Control Panel Extensions now allow you to
easily change printer drivers on-the-fly. (Results will vary
depending on how well-behaved the application is. Some
applications will require that you select the driver before
running it; well-behaved applications will allow you to select the
driver anytime before actually printing.)
5) Desk Accessories or Control Panel Extensions now allow you to
easily select or install other GDOS drivers and configure and
install fonts.
FontGDOS product support is provided in GEnie's Atari Roundtable,
Category 14, Topic __. You may also send e-mail to me (B.REHBOCK) or
Mike Fulton (MIKE-FULTON) if you have technical difficulties.
Developers that are interested in correctly providing application
printer output should contact Gail Bacani on 408-745-2022 to obtain
the latest GDOS application information. It is available to
registered commercial developers for free. United States and Canadian
residents that are interested in GDOS programming can order the "GEM
Programming Guide" from Atari Developer Relations for only $40.00
(US). The kit contains:
1) GEM Programming Guide,
Volume 1 -- VDI (Third Edition: January 1989)
Volume 2 -- AES (Third Edition: January 1989)
2) GDOS/FSM GDOS Developer Guide (10/91)
3) GEM Resource Construction Set (undated)
4) TOS Developer's Kit Disk #2: MicroEMACS / Source Code Examples / RCS
Simply send a check or money order for $40.00 and a note indicating
you would like to receive the "GEM Programming Guide" to:
Atari Corp.
1196 Borregas Ave.
Sunnyvale, CA 94089
Attn: Developer Relations/Material Order
Residents outside U.S. and Canada must contact their local Atari
Subsidiary for the kit.
Enjoy this latest operating system upgrade from Atari.

Introduction:
-------------
We should begin with a quick review of what GDOS is and what it allows you
to do. GDOS is actually an extension of your operating system. It allows
the programs that you run to output text and graphics to printers and other
devices besides the screen. GDOS also enables you to print text in many
different font faces. Instead of typing characters in the standard system
font, you now have access to Swiss, Times, Typewriter, and a multitude of
other fonts.
GDOS is run when you first turn on your machine. For now, don't worry
about where to put it or what it needs to run. Our install program will
set your system up so that everything will be placed in the correct
location.
Basic Concepts:
---------------
FontGDOS replaces the original GDOS. If you already have the original GDOS
installed on your system, then your first question is probably, "What's the
difference between the GDOS that I have now and FontGDOS"? The main thing
is that FontGDOS uses memory much more efficiently than earlier versions of
GDOS.
For example, with the original GDOS v1.1, if you had 18 fonts installed for
your printer, taking up 1.5 megabytes of disk space, then when your program
tried to load printer fonts, GDOS would load all 18 fonts and use up 1.5
megabytes of your free memory (unless you didn't have that much memory
available). This would be the case even if the document you were printing
only used 3 or 4 of the 18 total fonts.
One of the main new features in FontGDOS is "font caching". With font
caching, you tell FontGDOS how much memory that you wish to devote to
storing your bitmap fonts. This memory is called a cache. FontGDOS will
wait to load in a font from disk until when it's actually needed, and then
store it in the cache for quick access. When there is no longer any room
in the cache for the next font, FontGDOS will remove something from the
cache to make room. As long as the memory that you allocate for the cache
is bigger than the largest font, FontGDOS will be able to use as many
bitmap fonts as you wish in a limited amount of memory.
An even more enhanced version of GDOS known as FSMGDOS is available
separately for an additional charge. FSMGDOS uses special outline fonts
which can be scaled to any size or rotated at any angle without a loss of
quality (unlike bitmapped fonts). FSMGDOS also works with bitmapped fonts
like FontGDOS, but FontGDOS does not work with FSMGDOS outline fonts.
Contact your Atari dealer for information on obtaining FSMGDOS.
Getting Started
---------------
Installing FontGDOS onto your system is a simple task. Insert FontGDOS
disk #1 into your floppy drive. Run INSTALL.PRG on this disk to install
FontGDOS onto your system. The install program will walk you through the
steps needed to install FontGDOS. When the installation is completed, you
will have all of the necessary files on your system to begin. (The
install program is the same for both FontGDOS and FSMGDOS. Make sure you
select FontGDOS for installation unless you have FSMGDOS.)
After the installation is completed, you must reboot your machine to enable
FontGDOS. If you've installed it correctly, you'll get the new FontGDOS
sign-on message while you boot up. If all went well, FontGDOS was
installed and you should be seeing a normal desktop. If FontGDOS gives you
an error message while booting up, run the install program again, paying
close attention to any installation error messages which may come up. Note
that the installation program will install brand new device drivers, and
that old drivers for the original GDOS will not work correctly with either
FSMGDOS or FONTGDOS. (However, Atari supplies drivers for most popular
printers with FontGDOS and FSMGDOS.)
FontGDOS should be compatible with all programs that use the original GDOS.
Try running some of these programs to see how they work with FontGDOS.
Note that the installation program will set up your system so that you can
use all of your newly installed fonts immediately. To change the setup
(e.g. if you want to use older GDOS fonts from an earlier GDOS
installation), read the section below on how to use the FontGDOS Printer
Selector accessory.
Note: The remainder of the document will refer to accessories only, but in
all cases the same thing applies to both the Desk Accessory the
corresponding CPX modules as well. Refer to the documentation for
the eXtensible CONTROL Panel (XCONTROL) for more information on
installing CPX modules.
In addition to the FontGDOS program, three accessories have been provided:
