        The Amiga Guru Book - a reference manual

        [MODERATOR'S NOTE:  This is a serious review, but beware of
        subtle jokes...!  - Dan :-)]


        The Amiga Guru Book is a book about the Amiga and its operating
system.  It offers fundamental knowledge of the Amiga system and covers such
areas as: guidelines for proper multitasking programming, ANSI C, Aztec C
and SAS/C, debugging techniques, AmigaDOS, the file systems, the format of
load and object modules, process creation, CLI and user shells, handlers and
packets (more than complete list of packets), and many other areas.  There
are many useful bits and pieces about the OS that you'd have a hard time
finding anywhere else.

        The recommended price ("Unverbindliche Preisempfehlung") is
DM 79,- in Germany, which would convert to about $47 (US).



                No special hardware required.
                Compatible with all Amigas.


                Knowledge of English.


        Excessive manual-word-lookup copy protection.  Every time you use
the book, you CONSTANTLY have to look up words and whole sentences in the
manual.  The word lookup scheme is ingenious:  while using the product, you
don't normally notice that you're looking up the phrases! ;-)

        - The Amiga Guru Book (W6.7" x H9"   x D1.5")
                              (W17cm x H23cm x D3.7cm)
                              (about 1.2 kg)
        - 736 pages
        - coated cover
        - comes with its own documentation :-)


        After having bought "Das Amiga-Guru-Buch" several years ago by
the same author, I immediately went out and obtained the "Amiga Guru
Book" when I heard that Ralph Babel had finished it.

        The Amiga Guru Book is the successor to "Das Amiga-Guru-Buch" and
contains pretty much all of the original information (updated) and quite a
bit of new stuff.  Every chapter starts with a few quotes related to the
topic at hand.  For example, here is one of the quotes for the chapter "Legal
Alien:  AmigaDOS, the Englishman in the System":

        "BRAIN-DAMAGED. adjective.  Obviously wrong; extremely poorly
           designed; {cretinous}; {demented}.  There is an implication
           that the person responsible must have suffered brain damage,
           because he should have known better.  Calling something
           brain-damaged is really extreme. The word implies that the
           thing is completely unusable, and that its failure to work is
           due to poor design, not accident."

           -- Guy L. Steele Jr. et al., The Hacker's Dictionary

and another one for the chapter "Hooking in at Boot Time":

        "ColdCapture and CoolCapture vector operation will change because
        ExecBase can be in fast memory (the result of this is to raise the
        temperature of ColdCapture about 60 degrees)."

           -- Bryce Nesbitt, Compatibility Risks for 1.4 and Beyond

        The book can be used as a tutorial on programming the Amiga, but it
is also very useful as a reference manual.  The index looks like a VERY big
hash table. ;-)

        Throughout the book, you'll find quite a few assembly-language and
SAS/C listings to further the enlightment of the reader on a specific topic.
The code examples range from short fragments to complete working programs
(for example, the complete source code for a user shell). It would have been
a nice idea to offer a disk with all the sources to accompany the book; but
then again, the listings are meant to clarify certain subjects.  Therefore
this isn't a big problem.

        Among the many useful bits and pieces that you'll have a hard time
finding anywhere else are Amiga-specific information about the 68040;
compiler internals; system start-up procedures and different types of
reset-resident programs; CON custom-screen magic; user shells; FFS data
structures; and background information about BCPL, Tripos, and the Global

        The chapters on dos.library and DOS packets cover these subjects
much more in depth than anything else I've seen so far. The Guru Book
clarifies several ommisions and errors of the AmigaDOS Manual in regard to
dos.library, autodocs, packets and FFS data structures.  Included also is
information about DOS data structures and the program/process start-up

         About Listings


        The Guru Book's documentation is excellent.  It comes with a 31-page
index, so it's very easy to find a particular subject.  Obviously, the TeX
typesetting system was used in preparing the book and it really shows.
There's just one description of the quality:  excellent.


        There are lots of fun quotes, sideblows (many more than in its
predecessor) and interesting footnotes.  Ralph Babel reused some of the best
quotes from "Das Amiga-Guru-Buch".

        The book cover is now fully Style-Guide-compliant and displays a
normal 2.x window border and guru.

        The book is neither Zorro I/II or III compatible, and it doesn't fit
into the video slot nor the 3.5" and 5.1/4" bays of any Amiga.

        The book's resolution cannot be duplicated by any normal graphics
adapter for the Amiga.  At 1270 dpi it has an approximate resolution of 8509
* 11430 pixel.  The display is rock steady and non-interlaced.  All this is
monochrome, though.

        It is not hard disk-installable.

        Making a backup copy for safety reasons is a LOT of work.


        It completely replaces the Bantam AmigaDOS manual (though it doesn't
include the bugs... therefore if you liked them, you'll have to fall back on

        It is more fun than the Amiga ROM Kernel and Hardware Reference
manuals and has a better form factor.


        Immediately upon receiving the book I sprayed it with insecticide,
so I'm pretty sure that there are no bugs left... at least none alive.


        Ralph Babel can be found on several groups on USEnet, where he's
known and feared for his short/precise/crisp answers/flames.


        There's a pretty impressive disclaimer in the book that disclaims
all shapes/colours.  I didn't read it completely though, as reading Lawyer
Talk always gives me headaches (although you can find a joke in anything, if
you look hard enough).


        The Amiga Guru Book ranges somewhere between a specialized book and
light literature.  It is excellently researched, pleases the eye, and
contains numerous hints, tips, tricks, and knowledge nowhere else to be
found.  It is a must for every serious (and especially for the not quite so
serious) Amiga programmer.

        Don't walk, RUN out to your nearest book store and buy it.  Better
buy three copies:  one to use as a mousepad, one to keep the door closed,
and one to put under your pillow. ;-)


        All the typos above are mine, all mine. You can't have them, so
nyha, nyha ;-)
