  1 CPU, Custom chips, RAM and other stuff
  ****************************************

     This chapter contains questions concerning the Amiga-Hardware.

  1.1 What are the 68EC020 and the 68EC030?
  =========================================

     Motorola, the company producing the 680x0 family offers crippled
  versions of their processors. They are a little bit cheaper than the
  originals, that's why Commodore decided to build the 68EC020 into the
  A1200 and the 68EC030 into the A4000/030.

     The difference between the 68020 and the 68EC020 is that the latter
  can address just 16Mb of memory. That's why the A1200 cannot have more
  that 10 Mb RAM. In most cases you will not notice the difference.

     This is not the case for the 68EC030: Many owners will notice that
  the 68030 has an MMU and the 68EC030 doesn't have. There are some
  important programs depending on an MMU, for example Enforcer (a
  debugging utility), GigaMem (a program to emulate virtual memory) or
  all current Unix versions (see Unix). Other Amigas than the A4000 and
  the A3000 need an additional processor card to run these.

     Finally the 68LC040 is a 68040 without FPU. See FPU.

  1.2 What's an FPU?
  ==================

     The first 680x0 processors (upto 68030) could process integers only.
  Floating point operations had to be emulated by the software. An FPU is
  a chip (or part of a chip) that can process floating point operations, a
  mathematical coprocessor.

     One separates three FPU types on the Amiga: The 68881, 68882 and the
  68040's internal FPU. The 68882 is up to 1.5 times faster than the
  68881, because it is splitted in two parts: A conversion unit (the
  FPU's are using an 80 bit format internally) and the arithmetic unit.
  The 68040's internal FPU adds a pipeline, but misses the trigonometric
  instructions of the others. These are still emulated by the software,
  68040.library for example.

     Special programs (Raytracing, DTP, Mathematics, TeX) are offered in a
  special coprocessor version which are up to 50 times faster than the
  original versions.

     Michael Kaiser ([e-mail])

  1.3 Can I use a 3.5" HD in my A1200?
  ====================================

     Many people would prefer to use a 3.5" instead of the smaller 2.5"
  drives as the former are much cheaper. This is possible, but you need a
  special cable to connect the drive to your IDE controller. Additionally
  you should put some isolating material between the drive and the main
  board. Some people report termic problems but I did not notice anything.

     Some dealers offer a set which contains the cable, isolating material
  and for about 20$. See the magazines for more information.

  2 The Operating System
  **********************

     This chapter handles questions concerning the operating system,
  Kickstart as well as the Workbench.

  2.1 Can I use another Kickstart than the builtin?
  =================================================

     First let's drop some words on the Kickstart's Copyright: This
  belongs to Commodore, you *must not* use Kickstarts, without the right
  to do it!  Especially it isn't allowed to make an image of anyone
  else's Kickstart and run this on your own Amiga. (I even doubt that it
  is allowed to do this on your own Amigas, if you have more than one.)

     But of course it is possible and allowed for some people, developers
  for example.  There are two different ways, a hardware solution and a
  software solution.  The former is to buy a card which can hold two or
  more Kickstart ROMS and allows to select between when the System is
  booting.

     The software solution needs a program (softkicker) and an image of
  the ROM. The softkicker allocates RAM, loads the ROM image into the
  allocated memory and reboots. Of course you have less RAM after the
  Reboot: 256Kb when running Kickstart 1.2 or 1.3 and 512Kb for Kickstart
  2.0 or higher.

     There are different Softkickers, some of them needing a MMU (see
  68EC0xx). I recommend SKick 3.43 (Aminet, directory `util/boot')
  because it doesn't need a MMU and supports many different Kickstarts.
  It is rather easy to create the ROM image using the following program:

           #include <stdio.h>

           #define kickorig 0xf80000   /*  0xfc0000 for Kick 1.2 und 1.3   */
           #define kicklen  0x080000   /*  0x040000 for Kick 1.2 und 1.3   */

           void main(int argc, char*argv[])
           {
               FILE *fh;

               if ((fh = fopen("kickstart.file", "w"))  !=  NULL) {
                   result = fwrite(kickorig, kicklen, 1, fh);
               }
               fclose(fh);
           }

  2.2 What is the Amiga equivalent of . (Current directory)?
  ==========================================================

     The AmigaDOS equivalent for the . representing the current directory
  on Unix and certain non-reentrant interrupt handlers is the empty
  string, which is written as "".

     Example:
           COPY S:Startup-Sequence ""

  copies your Startup-Sequence to the current directory.

     There is some FD software available to patch a Unix-like
  interpretation of . and .. into the AmigaDOS, including, but not
  limited to, Martin Scott's UnixDirs. (Aminet,
  `os20/util/UnixDirsII.lha' or Fish-disk 837)

     Arno Eigenwillig ([e-mail])

  2.3 The PIPE: queue-handler
  ===========================

     In the AmigaOS release 2.04, a new handler for passing data between
  programs was introduced. This handler is called `L:Queue-Handler',
  better known as the `PIPE:' device.

     `PIPE:' implements a true `pipe' familiar from UNIX systems.  Its
  function is to pass the output of one program to another program as
  input. You can chain several programs together using multiple pipes.

     The advantages of using pipes are:
    1. No need for a lot of RAM to keep the temporary files, or, no need
       to slow things down by storing temporary files on the HD.

    2. Faster operation since the intermediate data doesn't need to be
       stored anywhere between programs.

     The `PIPE:' device differs from the UNIX pipes in two important
  respects:
    1. It is a device, so the input and output of the programs doesn't
       need to be a redirected standard output, although that is the
       general case. You can also use `PIPE:' instead of files, with two
       restrictions; you can not read a directory from `PIPE:', and the
       `PIPE:' `file' can not be `seeked' in.

    2. It does not support a flush operation. If all of the data written
       in a `PIPE:' device is not read out, it will stay there, buffered.
       Thus you must always `empty' a pipe before closing it.

    3. Because of the above, if unread data exceeds the size of the
       `PIPE:' internal buffer, the program writing to the pipe will
       `block' (that is, suspend operation) until the data is read. See
       below on how to manually flush a pipe.

     The PIPE: handler name syntax is `PIPE:name/bufsize/bufnum', where
  `name' is the name for the pipe channel. Using names you can have
  several simultaneous pipe operations. The optional arguments
  `bufsize'and `bufnum' specify the size and number of the buffers used
  by `PIPE:'. Normally, you would just use `PIPE:name'.

     The default buffer size of `PIPE:' is 4096 bytes, and the number of
  buffers (ie. channels) is unlimited.

     Osma Ahvenlampi ([e-mail])

  2.3.1 Using PIPE: in a standard AmigaShell environment
  ------------------------------------------------------

     First, make sure `PIPE:' is mounted. You can do this by giving the
  command
           1> Mount PIPE:

  in a Shell window. On an AmigaOS 2.1+ system, `PIPE:' is normally
  mounted on startup by placing the mount entry file `PIPE' in the drawer
  `DEVS:DosDrivers'.

     In an AmigaShell window, give the commands:
           1> Run List SYS: >PIPE:Listoutput
           1> More <PIPE:Listoutput

  (1)

     These two commands list the contents of the `SYS:' volume to a pipe
  and then type it in the Shell window. You could also use:
           1> Run List SYS: NOHEAD >PIPE:Listoutput
           1> Run Sort PIPE:Listoutput PIPE:Sortedoutput
           1> More <PIPE:Sortedoutput

  Notice that you need to `Run' all the programs except for the last one.
  This is so that you can get them all running simultaneously. You could
  also use several Shell windows, or any other way of running all the
  programs at the same time. Also this might not work if `More' isn't the
  standard Commodore AmigaOS 2.04+ More found in `SYS:Utilities'.

     In case you need to manually flush a pipe, for example because the
  program that was reading from it aborts prematurely, it can be done
  with the command:
           1> Type PIPE:name TO NIL:

     ---------- Footnotes ----------

     (1)  Note that `1>' is the prompt AmigaShell gives when it is
  waiting for a command. The number varies, and the prompt can be
  customised to look completely different. It is not a part of the
  command.

  2.3.2 The Pipe command
  ----------------------

     As you can see, this is a somewhat difficult way of using pipes,
  needing a lot of typing especially compared to the UNIX pipes. There is
  a solution for that.

     Andy Finkel, a former Commodore software engineer wrote a command
  called `Pipe' (not to be confused with `PIPE:') that simplifies the use
  of the `PIPE:' device. Unfortunately, this command did not make it into
  the 2.04 release. However, Commodore has given the permission to
  distribute this, and a few other commands, freely. (Sources: Fish disk
  637, Aminet, `util/cli/finkelshelltools.lha')

     For some reason Commodore did not include these commands in the later
  OS releases, although they work fine even with OS 3.1 (V40). Thus all
  users are required to get them from the above sources if they wish to
  use them.

     The Pipe command usage is simple. The commands to be run with their
  inputs and outputs piped together are given as arguments to the
  command, separated by the | (vertical bar) character:

           1> Pipe List SYS: | More
               or
           1> Pipe List: SYS: NOHEAD | Sort IN: OUT: | More

  Notice how Sort needs `IN:' and `OUT:'. These devices don't actually
  exist, but the Pipe command simulates them with the PIPE:. This is
  necessary because C:Sort can not use the `standard IO', but insists on
  files.

     The separator character | can be configured to be something else
  with the local variable __PCHAR.

  2.3.3 Pipe command support in AmigaShell
  ----------------------------------------

     There is a little known and quite useful undocumented feature built
  in the 2.04+ AmigaShell, that is, AmigaShell knows about the `Pipe'
  command. By setting the local variable _PCHAR, you can use pipes
  without even entering the Pipe command. AmigaShell will prepend it on
  the command line automatically if it sees the pipe separator command
  specified by _pchar on the command line.

     Thus, after the command:
           1> Set _pchar "|"

  (1)

     the above examples can be used like this:
           1> List SYS: | More
               or
           1> List SYS: NOHEAD | Sort IN: OUT: | More

     Those familiar with the UNIX pipes will notice how the usage is very
  similar to the UNIX pipe usage.

     ---------- Footnotes ----------

     (1)  The quotes around the vertical bar are important, to avoid
  AmigaShell interpreting the command as an attempt to use PIPE:, if
  _PCHAR is already set (for example if the Shell is started from within
  another one).

  2.3.4 Quick usage guide
  -----------------------

    1. Get the ShellTools archive from the Fish disk 673, or from Aminet,
       `util/cli/hacks204.lha'.

    2. Install the commands in this archive in your Shell search path,
       preferably C:.

    3. Put the command `Set _pchar |' in your `S:Shell-Startup' file.

    4. Restart your AmigaShell so that it reads the `S:Shell-Startup'.

    5. Try `List SYS: | More'

    6. Read the ShellTools documentation and experiment.

  2.3.5 Related things
  --------------------

     The variable _mchar is used to separate one command from another in
  a shell line.  So, after the command:
           1> Set _mchar ";"
     you can put more shell commands into the same line, separated from
  each other by `;'.

  2.3.6 Troubleshooting
  ---------------------

  *Q:*
       When I try the command `List SYS: | More' I get an error
                PIPE: Unknown command

       I have `PIPE:' mounted, what's wrong?

  *A:*
       AmigaShell is referring to the command `Pipe' in the error, not the
       `PIPE:' device. You haven't installed the commands in the
       ShellTools archive.

  *Q:*
       I get a requester that says
                Please insert volume PIPE: in any drive

       when I try any of the command examples.

  *A:*
       `PIPE:' is not mounted. Try `Mount PIPE:'. If that doesn't work,
       refer to your AmigaDOS manual or a friend that knows how to mount
       devices.

  *Q:*
       When I try any of the examples the More window pops up but nothing
       is shown/I get an error afterwards/More pops up a file requester.

  *A:*
       You are not using the standard AmigaOS `More' command. Either use
       another name or install a command that supports pipes.
       Possibilities are the C= More, Less, or Most for example.

  *Q:*
       None of these happen but it still doesn't work as you described.

  *A:*
       Are you using OS 2.04 later? Are you using the standard AmigaShell?
       Try with all extras disabled.

  3 Programming
  *************

     This chapter handles problems arising for programmers and
  compiler-users only.

  3.1 What documentation do I need as an Amiga programmer?
  ========================================================

     The best information available are the RKMs (ROM Kernel Manuals), 3rd
  edition, by Commodore, published by Addison-Wesley:
       The Amiga ROM Kernel Manual:  Libraries, ISBN 0-201-56774-1
       The Amiga ROM Kernel Manual:  Devices, ISBN 0-201-56775-X
       The Amiga ROM Kernel Manual:  Includes and Autodocs, ISBN
                                                            0-201-56773-3
       The Amiga Hardware Manual, ISBN 0-201-56776-8
       The Amiga User Interface Style Guide, ISBN 0-201-57757-7

  Especially the RKM: Libraries is a must. The RKM: Includes and Autodocs
  isn't that much worth: Better get the same stuff on disk instead to
  have it online.  See Includes.

     AmigaDOS isn't included in these books. The Autodocs give much
  information, but to go deeper you probably need
       The AmigaDOS Manual, 3rd Edition, ISBN 0-553-35403-5
     published by Bantam Books.

     A better choice for developers is
       The Amiga Guru Book

  by Ralph Babel. The book starts with a survey on different aspects of
  programming the Amiga. (About 250 pages) Useful for beginners are the
  sections on the Amiga's data types (not to be confused with the 3.x
  DataTypes used by MultiView, for example), the Includes and the
  amiga.lib. But even experienced programmers will find useful things
  here that are missing in the RKMs.  But the largest part are about 500
  pages on AmigaDOS and, as I think, the most important, because AmigaDOS
  is the worst officially documented part of the OS. The book is rather
  concise and hence not as easy to read as the RKMs, but I recommend it
  as an addition and instead of the AmigaDOS manual.  (Not, however, a
  replacement for the Libraries and Devices, which aren't covered here.)
  Unfortunately the book has no ISBN and is available in special stores
  only. But there are some mail order companies which offer it for about
  50$ and which accept credit cards:

     See FAQs.

  3.2 What is CATS?
  =================

     This is a department at Commodore West Chester which was formerly
  named `Commodore Amiga Technical Support' and was later renamed
  `Commodore Application and Technical Support'. These are people that
  work independently of Engineering, but close together with them, and try
  to help developers outside of Commodore to create nice Amiga
  applications, software or hardware. To achieve this, CATS has gathered
  a lot of informations and tools, on floppy, CD, or paper. Much of this
  material is also available to the general public. (1) But don't mix
  this up with some sort of Hotline for everyone!

     For Americans the address to get this material is
           CATS - Developer Applications
           Commodore
           1200 Wilson Drive
           West Chester, PA. 19380

  for all Europeans it's a company in Germany:

     Dr. Peter Kittel, [e-mail]

     ---------- Footnotes ----------

     (1)  Which means: For Non-Developers.

  3.3 Where do I get the Amiga includes?
  ======================================

     The only legal way to get the includes and autodocs (and you *should*
  get them, they are *very* useful!) is to become a developer (see
  Developer) or to buy the `NDU' (Native developers update kit, also
  known as `NDUK' or `NDK'), which is offered by CATS. They cost about
  30$ plus shipping and this seems to me to be a fair price. See CATS.
  The current version is 3.1.

     If you need only the includes, you could get them as well with a
  compiler (commercial compilers only) or by getting the Fresh Fish CD.
  See Fish CD.

  3.4 How do I become a developer?
  ================================

     You need the `ADSP' (Amiga Developer Support Program) documents. To
  get this write a letter to your local Commodore branch asking for these
  documents.  Everything else should be explained there. The german
  address (for the US address see CATS) is
           Commodore
           Lyoner Strasse 38
           60528 Frankfurt
     There are three different developer versions:
  *Registered*
       developers get access to the CBMNET (kind of a Commodore-internal
       Usenet), which makes it possible to discuss problems with other
       developers, Commodore engineers included. Registered developers
       pay about US$80 per year, plus initial US$30 initially.

  *Certified*
       developers seem to me the most interesting claass: They have the
       possibility copy the most beta versions of the system software
       (Kickstart and Workbench) and the respective Includes and
       AutoDocs. (Not all beta versions and especially no beta hardware.)
       You pay about US$250 per year plus US$50 initially for this.

  *Commercial*
       developers finally have in most details the same as certified
       developers, but may expect to get more beta versions and sooner,
       included beta hardware (This has *not* always been so in the
       past.), hencethey pay about US$400 plus US$50 initially.

  The above describes the prices and the situation in Germany and might be
  different elsewhere. Especially not all Commodore branches offer the
  registered status. A hint is to build a group of users and become a
  developer group, so the costs are reduced.

     All developers have to sign non-disclosure agreements (`NDA') which

  3.5 What compilers (assemblers) are there?
  ==========================================

     There is a lot of programming languages on the Amiga, commercial as
  well as freely distributable. I will enumerate only those that I know
  or which seem it worth to me otherwise.

  *Assembler*
       All C-compilers have an Assembler included. Freely distributable
       are A68K and PhxAss (directory `dev/asm' on Aminet or Fish disks
       521 and 906)

  *C*
  *C++*
       Freely distributable C-compilers are `gcc' (which has its own
       directory `dev/gcc' on Aminet) and the evaluation version of
       `Dice' (for example per FTP from `ftp.uni-paderborn.de', directory
       `/news/comp.binaries.amiga/volume91/languages' or on Fish disk
       491).  The advantage of gcc is that you find gcc versions all over
       the world and on all computer systems. Another advantage is that
       C++ is included into gcc! But it is slow and needs 4Mb of RAM or
       more.  See The GNU C compiler.  See Mailing lists.

       Commercial C compilers are `Aztec-C', `Dice' and `SAS/C'.
       `Aztec-C' doesn't seem to get further development any more.  It
       should be remarked that the commercial compilers have especially
       wonderful debugging utilities (Source level debuggers!) that the
       others are missing.

       SAS/C has announced to drop support of the Amiga-Compiler, too,
       due to the Amiga's bad situation. However, the compiler is still
       available and up-to-date and has a crosscompiler included, which
       translates C++ to C and supports the source level debugger too.
       Considering the price of just 99$ for students and updates from
       recent versions or other compilers it is still the most
       recommendable of the three. In europe the compiler is available
       from
                SAS Institute GmbH
                PO Box 10 53 40
                69043 Heidelberg
                Germany

                Phone: [phone]
                EMail: [e-mail]

       Dice is the cheapest and fastest commercial compiler. The greatest
       disadvantage of Dice (compared to the other commercial compilers)
       is the so-called Source-Line-Debugger: This means that you see the
       current line of source and can execute the program step by step,
       like with the other debuggers. On the other hand you can examine
       memory only, not the variables.  To get information about DICE,
       send email to [e-mail]. An automatic system will return
       complete details, including upgrade prices.

       Comeau C++ is a crosscompiler like SAS/C++. That wouldn't be a
       problem, but Comeau C++ doesn't have a C compiler included.  You
       need SAS/C, Aztec-C or Dice additionally. But it is AT&T cfront 3.0
       compliant and supports exceptions. And like gcc it runs on many
       platforms.  Maxxon C++ is offered in Germany. I cannot say
       anything on it. Both compilers are commercial. Comeau's address is:
                Comeau computing
                91-34, 120th Street
                Richmond Hill, NY, 11418-3214
                USA

  *Forth*
       JForth is said to be an excellent Amiga port of Forth. Among its
       advantages are object oriented extensions, full Amiga interface
       and an application generator. It is available from:
                Delta Research
                P.O. Box 151051
                San Rafael, CA   94915-1051

                EMail: Phil Burk, [e-mail]
                       Mike Haas, [e-mail]

  *Fortran*
       (Sigh! Still people who need it :-<) Freely distributable are BCF
       (Fish disk 470) and f2c, a Fortran to C converter (Aminet,
       directory `/dev/misc'). A commercial compiler is offered from
       ABSoft. All these are Fortran 77 compilers, I don't know any
       Fortran 90 compiler on the Amiga.

  *Lisp*
       Freely distributable Lisp interpreters are XLisp (Fish disk 181)
       and OakLisp (Fish disks 519 and 520) and CLISP
       (`/pub/lisp/clisp/binaries/amiga' at the server `ftp
       ma2s2.mathematik.uni-karlsruhe.de'). Lisp compilers are Gambit
       (Fish 764 and 765) and Scheme-to-C (Fish disks 556, 557 and 558).
       See Mailing lists.

  *Prolog*
       `/dev/lang/UNSWProlog.lha' and `dev/lang/sbp3_1e.lha' on Aminet as
       well as `SBProlog' on Fish disk 141 and `SBProlog' on Fish disk
       145 are freely distributable Prolog interpreters.

  *Modula-2*
       M2Amiga is offered in Europe, Benchmark Modula-2 in the U.S. Both
       are said to be very good, have a powerful source-level-debugger, a
       large library.  Especially M2Amiga has great support by a german
       user-group (AMOK) which for example offers own PD disks. See
       Mailing lists.

       M2Amiga is offered by:
                A+L AG
                Daderiz 61
                2540 Grenchen

                Fax:              -79

       Benchmark Modula-2 is available from:
                Armadillo Computing
                5225 Marymount Drive
                Austin, Texas 78723

                EMail: Jim Olinger, [e-mail]

  *Oberon*
  *Oberon-2*
       Two compilers (both Oberon-2) are available: AmigaOberon
       (commercial) is offered by the same company as M2Amiga. It is
       integrated into a full developers environment and has a large
       library of modules.  Library linker and  source level debugger are
       available.

       Oberon-A is a Freeware compiler. (Source: Aminet, `dev/obero'
       directory) However, this is a beta release, especially the module
       library is limited. See Mailing lists.

       The AMOK user group supports AmiOberon as well as M2Amiga.

  *Pascal*
       There is a PD-compiler called PCQ (Directory `dev/lang' on Aminet
       or Fish disk 511). It doesn't support all of Pascal and major
       features are missing. P2C, a pascal to C converter is on disk 341.
       (Aminet: `/dev/misc/p2c120.lha') Additionally there are two
       commercial compilers called HiSoft Pascal and KickPascal. HiSoft
       Pascal and P2C claim to be compatible to Turbo Pascal up to 5.0.
       HiSoft has a source level debugger included.

  3.6 Those never working Esc sequences!
  ======================================

     Many printers come with a manual that explains which Esc sequence
  causes which action on the printer. But there happen weird things when
  you try to send these sequences to your printer, either it does
  nothing, or it does something completely different. There is a reason,
  the Amiga printer drivers. These drivers are made in a way that they
  only understand a certain set of `ANSI Esc sequences', not the special
  ones defined (differently) by the various printer manufacturers. The
  purpose is that every application on the Amiga just uses this one
  standard set of control sequences and this way doesn't need to know
  which printer is actually connected. The printer driver then translates
  these standard sequences into the special sequences a certain printer
  understands.  A list of the available ANSI Esc sequences is found in
  the current Workbench manuals (or older AmigaDOS manuals). Now if you
  want to issue a control sequence to the printer that's not available as
  an ANSI command, you have two possibilities to achieve this:
    1. Bypass the printer driver (that would unsuccessfully try to
       interpret the sequence) and send your output *only* during this
       sequence to `PAR:' (or `SER:', respectively). For this you have to
       close and open printer output channels very often which is rather
       tedious, and you have to know where (`PAR:' or `SER:') your
       printer is connected.

    2. Use a special ANSI sequence, made exactly for this case:
                `Esc[<n>"<x>'
       where `<n>' is the decimally typed number of bytes in the string
       `<x>', which actually contains your special printer sequence. This
       ANSI sequence tells the printer driver to not interpret or
       translate the next `<n>' bytes.
          But both methods have one big disadvantage when used in an
  application program: You lose the printer independency! If you stick to
  ANSI sequen- ces, you can output to any printer on earth, as long as
  there is an Amiga printer driver for it. If you start to use special
  control sequences, your program will be tied to this single printer
  model and will not be usefull for any other (or you would have to
  provide some dozen new printer drivers for your application).

  3.7 Is it possible to use AmigaBasic on the A1200?
  ==================================================

     We heard conflicting reports about AmigaBasic on the A1200: While I
  said that you can work sufficiently with it, others said that this
  isn't possible, as AmigaBasic crashes on the slightest little error.  I
  couldn't reproduce this.

     Now I can. It depends on the setting in the Sound Prefs editor. When
  you activate a sound there, this conflicts with sound that AmigaBasic
  tries to produce by hand and obviously not quite the correct way itself.

     Easy solution: To work with AmigaBasic on the A1200, just
    1. Switch off sound output in the Sound prefs editor.

    2. On the A4000 (as well as on an A1200 with Fast Mem expansion (1))
       you  additionally need to run NoFastMem.

    3. Better avoid SUBs and use conventional GOSUBs instead, then the
       compatibility with newer processors will be higher.

  3.8 How do I localize my program?
  =================================

     Suggest, you want to write a `HelloLocalWorld.c'. Your final program
  will look like this:

           #include "HelloLocalWorld_Cat.h"
           #include <clib/exec_protos.h>

           struct Library *LocaleBase;

           void main(int argc, char *argv[])

           {
               /* Open the locale.library. No kill, if not successfull.
                  (Just use the builtin catalog strings instead.) Note, that
                  we open locale.library here, even if our compiler supports
                  AutoOpening.
               */
               LocaleBase = OpenLibrary("locale.library", 38);
               OpenHelloLocalWorldCatalogs(NULL, NULL);

               printf(GetString(MSG_Hello));

               CloseHelloLocalWorldCatalog();
               if (LocaleBase) CloseLibrary(LocaleBase);
           }

     The routine GetString checks, if the wished catalogs are available
  and returns a pointer to either the builtin string or the catalog
  string. (In my case the german string.)

     You see, the main difference besides the minor opening and closing
  stuff (OpenLibrary, OpenHelloLocalWorldCatalogs, ...) is to replace
  strings with a function call. Hence we need a file
  `HelloLocalWorld_Cat.c', which holds OpenHelloLocalWorld, GetString,
  CloseHelloLocalWorld and the builtin strings (this could be an array,
  where
               array[MSG_Hello] = "Hello, local world.\n";

  is defined) and an include file `HelloLocalWorld_Cat.h', which defines
  the message ID's like MSG_Hello. You don't need to know, how these files
  work internally, especially you don't need to know `locale.library'!

     There are some catalog generators (in what follows: CGs) available
  (`CatComp', for devlopers only, `KitCat', german docs only, `MakeCat',
  which I don't know and `FlexCat', which I  recommend, because it is
  most flexible in the generated source and supports catalogs on 2.0 and
  any language, even Amiga-E, Cluster, Pascal, ... and besides that: I'm
  the author ;-) are tools, that create  HelloLocalWorld_Cat.h,
  HelloLocalWorld_Cat.c and the real catalogs for you. (The above code
  might differ slightly between the different CGs.) (See Aminet, directory
  `dev/misc'.)

     Of course they need to know how to use them. First create a so-called
  `catalog-description' file. This could look like this:
           ; Lines beginning with a semicolon are comment lines.
           # language english
           ; the language of the builtin strings
           # version 0
           ; the catalog version (0 = any)
           MSG_Hello (1/15/30)
           Hello, local world

  Any string is defined by a line like the last two lines above: MSG_Hello
  is the message-ID, (1/15/30) says, that the value of MSG_Hello should be
  1 (you may omit this, in which case just the next free number is used)
  and the string must not be shorter than 15 characters or longer than 30
  characters. (These may be omitted too.)

     Now write your program. Once you are ready, use the CGs to create a
  so-called catalog translation file. (One for any language different than
  the builtin.) In my case (german) this could look like this:
           ; Lines beginning with a semicolon are comment lines.
           ## language deutsch
           ; the catalog language (german)
           ## version $VER: Deutsch.catalog 1.0 (22.12.93)
           ; the catalog files version string
           MSG_Hello

           ; Hello, local world

  Note the empty line after the message ID. (The arguments of ## language
  and ## version would be missing as well.) You have to fill in the
  german strings here. Again using the CGs you create a catalog file from
  this. Additionally note, that no informations on the strings ID or
  length are behind MSG_Hello.  They are taken from the catalog
  description file.

     Once you change the program (adding strings, changing the string
  length) you change the catalog description as well, use the CGs in the
  same way to update the catalog translation and hence the catalogs.

  3.9 How to obtain a pointer to a console's window
  =================================================

     The following function returns the window pointer of a CON window.
  It can be executed safely under all versions of the Amiga's OS.

         struct Window *getConWindowPtr(BPTR fh)
         {
           struct Window *w;
           struct FileHandle *cfh;
           struct StandardPacket *sp;
           struct InfoData *id;
           struct MsgPort *mp;

           w = NULL;

           if ((cfh = BADDR(fh))->fh_Type != NULL) {
             if (sp = AllocMem(sizeof (struct StandardPacket),
                               MEMF_PUBLIC | MEMF_CLEAR)) {
               if (id = AllocMem(sizeof (struct InfoData),
                                 MEMF_PUBLIC | MEMF_CLEAR)) {
                 if (mp = CreatePort(NULL, 0)) {
                   sp->sp_Msg.mn_Node.ln_Name = (char *) &sp->sp_Pkt;
                   sp->sp_Pkt.dp_Link         = &sp->sp_Msg;
                   sp->sp_Pkt.dp_Port         = mp;
                   sp->sp_Pkt.dp_Type         = ACTION_DISK_INFO;
                   sp->sp_Pkt.dp_Arg1         = MKBADDR(id);

                   PutMsg(cfh->fh_Type, &sp->sp_Msg);
                   (void) WaitPort(mp);
                   (void) GetMsg(mp);

                   if (sp->sp_Pkt.dp_Res1)
                     w = (struct Window *) id->id_VolumeNode;

                   DeletePort(mp);
                 }
                 FreeMem(id, sizeof (struct InfoData));
               }
               FreeMem(sp, sizeof (struct StandardPacket));
             }
           }

           return w;
         }

     Notes:
     * Accessing a console's window directly may interfere with operations
       performed by the CON handler. Be careful!

     * To obtain the window pointer of a CLI's console, pass the
       FileHandle returned by Open("*", MODE_OLDFILE) to the above
       function.

     * The result of the above function may well be NULL, e.g. in case of
       an AUX handler or if an AUTO CON handler is unable to open its
       window.

     * Sending an ACTION_DISK_INFO packet to an AUTO CON handler (2.0+)
       causes its window to lose its special AUTO properties (i.e. it can
       no longer be closed at any time by clicking on its Close gadget),
       as the window pointer returned in id_VolumeNode must remain valid
       from now on.

     * All in all: Don't use this function. :-)

     For more information, please refer to pages 273, 276, 435, 463, 485,
  and 629 in "The Amiga Guru Book" (see Manuals).

  3.10 What are pragmas?
  ======================

     Pragmas are special compiler commmands which control certain
  features of a C-compiler. Two problems arise when using pragmas:
    1. Pragmas are compiler specific. You cannot expect that one compiler
       will understand pragmas of another compiler, even if both run on
       the Amiga.

    2. You are not guaranteed that a compiler ignores pragmas, that he
       doesn't understand. Even more: It might not help, to use something
       like this:
                #ifndef MY_COMPILER
                #pragma DoAnything
                #endif

  A workaround is to put pragmas in a special include file (BTW, the same
  holds true for statements like #asm (Aztec-C) or #extern (C++) and
  replace the above with
           #ifndef MY_COMPUTER
           #include <mypragmas.h>
           #endif

     But what do pragmas on the Amiga? The most common usage (not the
  only, but most meant when talking about pragmas) is to tell the
  compiler about how to call library functions: Simple C functions expect
  their arguments on the stack, but library functions want their
  arguments in special processor registers and additionally the `library
  base' in register a6. Lets have a look at a pragma command of the
  Aztec-Compiler.
           #pragma amicall(SysBase,0xd2,FreeMem(a1,d0))

  This tells the compiler to put the first argument of FreeMem in register
  a1, the second in register d0 and the value of the variable SysBase in
  register a6. Maxons pragmas look the same, Dice pragmas and SAS pragmas
  look a bit more complicated;
           #pragma libcall SysBase FreeMem d2 0902

  Here d2 is (like 0xd2 above) the `library vector offset' (see below),
  the digits 09 are codes for the argument register in reversed order
  (Register codes are 0=d0, 1=d1, .., 8=a0, 9=a1, a=a2, ..), the
  following 0 is the result's registerä(always d0))and the final digit 2
  is the number of arguments.

     A command `FreeMem(fib,sizeof(*fib);' could produce the following
  code, if the compiler has seen a pragma statement like above:
           move.l  _fib,a1
           move.l  260,d1        ; sizeof(struct FileInfoBlock)
           move.l  _SysBase,a6
           jsr     -0xd2(a6)       ; 0xd2 = _LVOFreeMem

  Calling FreeMem in that way is shorter and faster than pushing the
  arguments on the stack, calling a function _FreeMem which would do just
  the same like the above code by pulling the arguments from the stack.

     The best way to use pragmas is to include statements like the
  following in your program:
           /*    Get the prototype for the function; note, that this is    */
           /*    compiler independent.                    */
           #include <clib/exec_protos.h>

           /*    Get the pragma; compiler dependent, but most pragmas    */
           /*    are in files with the same name.
           #ifdef AZTEC_C
           #include <pragmas/exec_lib.h>
           #endif
           #if defined(__SASC) || defined(_DCC) || defined(__MAXON__)
           #include <pragmas/exec_pragmas.h>
           #endif
           #ifdef __GNUC__
           #include <inline/exec.h>
           #endif

  The above example can be compiled on all these compilers and produce the
  best code.

     A final question arises: How to get the pragmas? Most compilers have
  them included. However, sometimes you want to produce pragmas for
  yourself, for example if you are using new libraries or new versions
  with additional functions. In that case you can produce them from the
  so-called `FD' files which should be a part of the developer docs of
  the library. (The NDU has a directory FD which contains FD files for
  all libraries and devices of the OS. see Includes) Most compilers have
  a utility with the name `fd2pragma' or similar included which can do
  that for you. A freely distributable version which can produce pragmas
  for Aztec, Dice, SAS and Maxon as well as LVO files for assembler and
  stub routines for the tag versions is available on Aminet
  (`dev/misc/fd2pragma2_0.lha' and on the Fish CDs.

     For pragmas under gcc see Inline Headers.

  3.11 My Compiler/Linker is complaining about missing symbol xxx.
  ================================================================

     First be sure, that the function is really missing: For example
  floating point functions are in a special link library and you need a
  linker option like `-lm' to include it into your program. Another
  possibility would be that you are using a library function and didn't
  notice it. This might lead to a missing library base, `IntuitionBase'
  for example. In that case just put something like
           struct Library *IntuitionBase;

  somewhere in the global part of your program. (Don't forget to call
  OpenLibrary() and CloseLibrary! :-)

     However, you could as well use a function which really isn't present
  in your library at all. If you have, for example, an amiga.lib from 2.0
  you would hardly find the locale functions or the pool memory
  functions. (1) Best solution is to get the NDU (see Includes), but you
  probably don't want to wait for it. In that case you have to find what
  kind of function you are missing.
     * Simple library functions (Examples: `exec/AllocPooled',
       `locale/OpenCatalogA') can be called with pragmas. However, you
       need informations on the name of the library base and where to put
       the arguments. See Pragmas.

     * Tag functions are mostly just stub functions which call library
       functions. If you have, for example, `dos/AllocDosObject' which
       expects a constant and a pointer to an array of tags, you have the
       varargs version `AllocDosObjectTags' which expects tags on the
       stack as well! Just create the following function:
                #include <clib/dos_protos.h>
                #include <pragmas/dos_pragmas.h>    /*  Probably wrong name */

                void *AllocDosObjectTags(ULONG objtype, Tag tag1, ...)
                { return(AllocDosObject(objtype, (struct TagItem *) &tag1);
                }

     * Some functions still remain: Amiga.lib has some functions which
       are really doing valuable things and not just call a library: The
       BOOPSI functions (`DoMethod', `DoSuperMethod') the memory pool
       functions (`LibAllocPooled', `LibCreatePool', which are
       replacements of 3.0 functions). The only way to replace these is
       to get equivalents. The AmigaFAQ archive contains some of them
       (DoMethod, DoSuperMethod and HookEntry) in the `programmer'
       directory as well as the most common pragma files and some
       examples of varargs functions. See Amiga-FAQ Archive.

     ---------- Footnotes ----------

     (1)  This problem arises most frequently for owners of Aztec which
  is no longer supported and owners of Dice, which has sometimes rather
  incomplete libraries. I own both ...

  3.12 Where do I find the function xxx?
  ======================================

     If you are not sure about the name of the appropriate function for a
  certain job or in which library to find it, you can search in these
  places:
     * In the Autodocs for each library you find at the very beginning a
       contents table listing all functions available in this library.
       They are sorted alphabetically, just like in the rest of the
       Autodocs.  In the body part of the Autodocs you find complete
       explanations and specifications for each library function. See
       Includes.

     * The .FD files also offer a very compact overview over all functions
       of the diverse libraries, complete with a short information about
       the function arguments. If you already know roughly what you
       search for and e.g. only need the precise order of the arguments,
       you can find all needed information here. See Pragmas.

  3.13 The GNU C compiler: general information and installation
  =============================================================

     This chapter contains general and installation information about the
  amiga-port of the GNU C compiler gcc.

  3.13.1 Current Version
  ----------------------

     The current version of gcc, further refered to as <gcc-current>, is
  2.5.8. Work is in progress for version 2.6 which will incldude a new
  version of the popular ixemul.library, the Unix system-calls emulation
  shared library, and a brand new C library avoiding gcc compiled programs
  to use ixemul.library.

  3.13.2 Requirements
  -------------------

     Any Amiga (ranging from A1000 upto A4000/40) will run amigados-gnu
  utilities. A minimum of 4MB memory is needed in order to compile
  small/medium projects. More memory will be needed for large projects,
  such as recompiling gcc itself, or programming C++. Gigamem is known to
  work with GCC so *maybe* less memory will work. But in this case, an
  MMU equipped Amiga (A3000,A4000/40) is necessary.  See 68EC0xx.

     A full installation, including C++/ObjC related files, inline
  headers, cbm-headers, (see Includes) roughly requires about 20 MB of HD
  space.

     Gcc will work under KS 1.2/1.3, but the full functionality is only
  available under KS 2.x+. A fast CPU (eg. 68030@25MHz or better) is also
  of help.

  3.13.3 Authors
  --------------

     Gcc and related GNU-software has been ported to the Amiga by the
  following folks: See How to get help.
           Gcc v2.2.2 port:   Markus Wild
           Gcc v2.3.3 port:   Markus Wild
           Gcc v2.4.5 port:   Philippe Brand, Lars Hecking, Fred Fish
           Gcc v2.5.0 and up: Philippe Brand, Fred Fish, Leonard Norrgard

           Ixemul.library:    Markus Wild, Leonard Norrgard, R. Luebbert
           Libnix:           Matthias Fleischer, Gunther Nikl
               Gerlib:            Gerhard Mueller

  3.13.4 Sources for Gcc
  ----------------------

     All GCC sources & binaries are available on:

    1. Aminet sites (wuarchive.wustl.edu and mirrors such as ftp.luth.se)
       in /pub/aminet/dev/gcc

    2. Ramses The Amiga Flying BBS:
                [phone]  HST Dual v32 terbo 4800-21600
                    [phone]  SupraFax v32bis    4800-14400
                    [phone]  Tornado v22bis     1200-2400
       in Topic `Development', Area `Gcc' (are 156).

     GNU source code is available on:

    1. the same FTP site you've taken the binary distribution from

    2. gnu.prep.ai.mit.edu (18.71.0.38) in `/pub/gnu'

    3. Ramses The Amiga Flying BBS in Topic
       `AmigaUnix/Unix/Linux/NetBSD', Area `Gnu Source Code'

     These archives should contain everything necessary to get you going,
  they don't include sources for ixemul.library, which are available on
  Aminet sites in `/pub/aminet/dev/gcc/ixemsrc3947.tar.gz' (as of this
  writing, work is in  progress for the v40 version of ixemul.library,
  sources will be available on an Aminet site near you).

     As stated by Richard Stallman of the FSF:

     "The GPL says that any distribution of binaries must contain either
  the source code or a written offer to supply source code (see the GPL
  for details of what is required)."

  3.13.5 Inline Headers
  ---------------------

     The inline headers for gcc can be created from the original CBM fd
  files.  See Includes. See Pragmas. They can be created as follows:

       CLI> Assign INCLUDE: GCC:os-include
       CLI> Assign FD: INCLUDE:fd
       CLI> Makedir INCLUDE:inline
       CLI> cd USR:bin/geninline
       CLI> gen31

     This will create all inline-headers in `GCC:os-include/inline'.  If
  you have 2.0 headers, use gen20 instead, if you have 3.0, use gen30.
  OS3.1 (rev 40.13) inline headers are included with <gcc-current>. See
  Current Version.

     NOTE: perl scripts do not handle correctly AmigaDOS include files,
  which seems to mean they are somewhat broken. This needs some voluntary
  work ...

     There is also another way of generating inline headers, using
  fd2inline program:

       CLI> fd2inline <fd_file> <proto_file>

  3.13.6 Amiga Libraries
  ----------------------

     Amiga-style libraries, such as amiga.lib, cannot be read by gcc
  directly. They need to be converted into a gcc-readable format using
  hunk2gcc, the AmigaDOS object converter made by Markus Wild.

     To achieve this, simply grab a copy of latest amiga.lib (from
  Commodore Development Kit, see Includes) and make a new directory where
  you want your converted object files to go, cd into it, and enter

           hunk2gcc amiga.lib [..further libs if you like..]

     This generates an a.out object file for every program unit present
  in the hunk file (in this case, from amiga.lib).

     As the final step convert all those files into an a.out style
  library by issuing:

           ar qc libamiga.a obj.*
           ranlib libamiga.a

     The ranlib run builds a symbol table in the archive, and makes
  accesses to the library much faster.

     NOTE: As long as you make no AmigaDOs specific calls, you can create
  a dummy library using:

         cat "int dummy;" >dummy.c
         gcc -c dummy.c
         ar crv libamiga.a dummy.o
         mv libamiga.a gcc:lib

  3.13.7 Installation
  -------------------

     IMPORTANT NOTE FROM Philippe Brand:

     As this is FAQ, most often asked question about gcc-2.5.8 is: "I
  can't compile C++ programs, what's up ?"

     In fact, I've messed up gcc-2.5.8 distribution. Instead of 2.5.8
  versions of C++ and Objective-C compiler passes, 2.5.7 versions were
  included. You've got here 2 options.

     - rename lib/gcc-lib/amigados/2.5.7 to 2.5.8 - get gcc258ud.lha on
  Aminet, which contains proper 2.5.8 versions.

     From Aminet get also gcc258ud1.lha which contains some fixed
  libraries, headers etc...

     And DON'T forget to grab gcc258-readme.lha also from Aminet.

    1. If this is your first installation of GCC:

            CLI> cd Disk_with_lot_space:
            CLI> lha x gcc258-x.lha

       (where x stands for 1 through 4, 5 & 6 if you want also to have
       sources)

       Now from the Workbench, invoke GCC-Install. This is what people
       wanted, e.g. an Installer based configuration script for GCC.

       Thus you only have to unpack archives and the installer script will
       do the rest, creating environment variables, adding assigns to
       user-startup, copy library and handler.

       BTW:

       Installer and Installer project icon (c) Copyright 1991-93
       Commodore-Amiga, Inc.  All Rights Reserved.  Reproduced and
       distributed under license from Commodore.

    2. If you "upgrade" your gcc environment from v2.x.x, well just erase
       gcc directory then go back to step 1. Too many stuff have changed.
       Just make sure you've backuped all what you've added to the GCC
       tree before.

     Note that you MUST use ixemul.library revision 45 and NOT revision
  47, as the latter doesn't check for ENV:

     You need to have a 50.000 stack size in order to compile with GCC.
  This should be enough for most projects. Note than while recompiling
  gcc with itself it has takeen more than 245KB stack. Stack can grow due
  to source complexity. Don't be afraid of it.

     To use ar and/or ranlib, you should have a much larger stack, between
  200.000 and 300.000, depending on library size.

  4 Applications
  **************

     This chapter offers informations about major Applications.

  4.1 Text Editors
  ================

     Text Editors are programs allowing to enter and edit unformatted
  text.  Generally, this means text that is meant to be manipulated by
  machine, rather than human. Programmers use these to enter the text for
  compilers.  Since UNIX machines don't typically have word processors,
  most text processing starts with a text editor, then is filtered
  through a page layout system (TeX, for example) to produce attractive
  paper results.

  *Commercial Products*
       CygnusEd Professional and TurboText seem to be the main contenders
       in the professional realm. The Fred Fish disks contain dozens of
       other shareware text editors. A demo version of TurboText is on
       Fish disk 445.  A very old demo of CygnusEd is on Fish disk 95
       (testament to its lasting-power). In the following some freely
       distributable editors will be discussed.

  *Emacs*
       Gnu Emacs (the "G" is not silent) comes from Unix and is probably
       the king of editors - it's huge (about 1 Megabyte), feature-packed
       (it does windows and even contains a game!) and extensible (if you
       know lisp you can write new emacs functions and bind them to any
       key combination).  On the other hand, it may be too huge, its
       feature-ladenness is imposing, and its extensibility often means
       you can't use someone else's emacs configuration. Source: Aminet
       (directory `util/gnu').

  *Vi*
       The leaner, less configurable, non-extensible cousin to gnu emacs
       is vi (pronounced "vee eye"). Unix people like vi especially
       because you find it on *any* Unix machine. What you choose is
       personal preference, and will mark you for life. Vim is a good vi
       for the amiga, and is on Fish disk 591 or in the `util/gnu'
       directory of Aminet.

  *DME*
       Many Amiga programmers like DME. It's fast, fully configurable;
       menus may be created and any key may be mapped. It's much easier
       to learn DME than than Emacs or Vi. There are three different
       versions: AmokEd, DME and XDME. It's a matter of opinion which you
       prefer. (Oberon and Modula programmers like AmokEd because it's
       written in Oberon and supports AmigaOberon error messages, C
       programmers like DME or XDME.) Sources: Aminet (directory
       `util/edit'), Fish disk 776 (XDME) and 749 (AmokEd), AMOK 90.

  4.2 What word processors are there?
  ===================================

     A word processor is the typical application for writing notes,
  letters or reports on a computer. Unless you prepare newsletters on a
  weekly basis, your word procesor is probably your workhorse program.
  Thus choosing one you are comfortable with determines how comfortable
  you are with your computer. Word processors can offer a variety of
  features, and many can approach the sophistication required for Desktop
  Publishing (see DTP) but no one uses them for programming, for which
  text editors are more suited.

     One distinguishes between Wysiwyg programs (What you see is what you
  get) and page layout languages. Wysiwyg programs should be fast,
  comfortable and easy to use. Most people prefer them. The alternative
  is an approach that works similar to compilers. You feed text files to
  a a program that produces the layout which may be previewed on screen
  or printed. LaTeX takes this approach. See TeX. Lout is another such
  system which seems smaller, easier to learn and has full documentation
  included, but it is nonstandard.  Lout produces Postscript output. (I
  don't know if this is an advantage or disadvantage. ;-) See Postscript.
  Both programs are freely distributable.

     There are a lot of wysiwyg programs, but only commercial products:
  FinalWriter, Final Copy II, Wordworth, Word Perfect, AmiWrite,
  Beckertext II, Maxon Word and many others. I don't dare to recommend
  any.  All I can say is: Give yourself time to make a selection.

  4.3 Desktop Publishing
  ======================

     These programs offer features lacking in word processors, usually
  tailored to flexible arrangement of text, but often don't provide all of
  the text manipulation that a good word processor provides. The best
  desktop publishing programs strive to provide the features of both,
  just as the best word processors strive to provide the features of
  desktop publishing programs. Microsoft Word (Mac, PC) is a good example
  of a word processing program that offers many page layout feature.
  Framemaker (UNIX, Macintosh, DOS, etc.) is an example of a desktop
  publishing system that offers most needed word processing functions. As
  yet, no Amiga program has bridged the gap, though the main word
  processors are coming close. (On the other hand, even many
  sophisticated programs don't support typesetting mathematics, tables,
  producing bibliographies, indexes, or cross-references. The page layout
  languages do, and programs like Frame are improving their support of
  such features.) Unless you need to prepare fancy newsletters or
  promotional literature, a word processing program is probably enough.
  See Word Processors.

     There are not yet any freely distributable wysiwyg desktop publishing
  systems. Commercial products are ProPage and PageStream. They have been
  playing leapfrog for the past few years. It appears that PageStream 3.0
  is about to leap ahead. A more detailed description of these products
  and their differences is welcome. Both programs' list prices are $299.
  Student discounts are available (approx 40% discount.)

  4.4 What is TeX and where can I get it?
  =======================================

     TeX is a very powerful wordprocessing system. It can display
  mathematical formulas or complex tables as well as function graphs,
  creates indices, contents and many other things. Its greatest advantage
  is that it is freely distributable (TeX, not the previewers and the
  printer drivers!) and that you find TeX all over the world on every
  computer family. Its greatest disadvantage is that it isn't very handy
  (works similar to a compiler) and it isn't wysiwyg. But many people
  like it. (BTW: This document is written using TeX. 8-) See Word
  Processors.

     There are two major implementations on the Amiga. The first one,
  Amiga-TeX, from Thomas Rockicki and Radical Eye software is commercial.
  It is said to be excellent and his owners seem to be very satisfied.
  But it costs at least 200$.

     I recommend PasTeX, a freely distributable version. People seem to
  have problems installing PasTeX, especially the font loading and
  generation (It's a quite complex program.) but I did not here anyone
  upset once it was installed. (A friend with knowledge of TeX helps
  immensely.) A few words should be said what you need:
     * 5 disks containing the TeX-compiler itself

     * 2 disks containing MetaFont

     * Nothing more Many people ask for fonts. They are included in the
  MetaFont-package and can get compiled by you. All you need to do is
  setting up your TeX-system in the right way which is described in the
  documentation. Please note that the PasTeX disks are compressed using
  the program Zoom. (see Endings) Sources: FTP at `ftp.uni-passau.de',
  directory `/pub/amiga/tex/PasTeX1.3' and the Fish CDs.

  4.5 Are there any Postscript interpreters?
  ==========================================

     PostScript is a programming language designed to be used to describe
  printing on pages. Apple helped make PostScript popular by selling
  printers with built in PostScript interpreters. Many programs have
  evolved to produce PostScript programs as their output, making
  PostScript the lingua franca of printing. Until recently, in order to
  print a PostScript file, you had to have a relatively expensive laser
  printer. The development that changed this was the software PostScript
  interpreter. These programs allow your computer to interpret PostScript
  programs, and produce the matrix of dots to send to your normal
  graphics printer.

     One of the benefits of PostScript is that it is resolution
  independent.  What this means is that it can support the highest
  resolution of your device - and that you can reasonably preview
  PostScript on a low resolution screen.

     There are two free PostScript interpreters for the Amiga. Post and
  Ghostscript. Post comes as an Amiga shared library along with front
  ends for previewing to the screen and printing. This structure allows
  others to write programs that can show PostScript images on screen. In
  fact, AmigaTeX uses Post's library to support incorporation of
  PostScript into documents.  Ghostscript similarly comes in two
  programs, but not as a shared library.  Ghostscript is the rendering
  engine, and Ghostview is the front end.  Sources: Aminet (directorys
  `text/print' and `text/dtp'), Fish disk 669

  5 How about Graphics?
  *********************

     Graphics is one of the major strengths of the Amiga. Why don't we
  have more answers here? :-(

  5.1 What are chunky and planar displays?
  ========================================

     Simply put, the terms `chunky' and `planar' (short for `bitplanar')
  refer to different ways of storing graphics information in a computer's
  memory. They are rather easy to understand, as far as things go, but
  incredibly difficult to explain:

     Computer images are arranged as a grid of pixels, each of which can
  be thought of as a number representing the color number of the pixel,
  sort of like a paint-by-numbers scheme.  For example, here's a
  simplified example image, in four colors:

          00302132

     The Amiga stores this image in a `bitplane' mode. That is, it is
  represented by several planes of bits (binary digits, 1s or 0s). This
  is a four-color image, so each color number could be represented by two
  bits.  Therefore there are two bitplanes:

          00100110    Here's bitplane 0
          00101011    And here's bitplane 1
          --------    Now, let's add them up, binary style:
          00302132

     Which is the final image. If the image was in two dimensions, it
  would truly be composed of bit planes. However, I'd need three
  dimensions to show multiple bitplanes overlayed, and therefore for
  simplicity we're working in one dimension (which is all we need).

     Now, there's another way of storing this image.  How about if we
  localize the bit data in little chunks?

          00 00 11 00 01 10 11 01 = 00302132

     This is the principle of the `chunky' pixel mode.

     Both methods of image storage are perfectly logical, and no one can
  say that one is better than the other. However, there are certain
  technical aspects which cause certain advantages and disadvantages.

     First, if you've seen colored text scroll on your Amiga, you know
  there is a bit of "flicker" that arises. Specifically, what happens is
  that while the text is scrolling, its color temporarily changes to
  something completely different. What's happening is that the computer's
  moving several bitplanes of data while the raster (monitor electron
  gun) is sweeping across the screen. What that means is that, if the
  raster catches the data while it's being moved, you can end up with some
  bitplanes being moved and some not. What if we filled bitplane 1 in the
  example above with 0s? Instantly all the 3s become 1s, and the 2s
  become 0s! This is what causes "flicker" when certain colors are
  scrolled. By contrast, if a chunky pixel display is caught while
  scrolling, all we see is a partially-scrolled image; the colors are
  preserved (since their units are the small ones).

     That's a disadvantage to planar pixels, but what about chunky pixels?
  Well, recall that a computer organizes information in terms of 8 bit
  bytes. These groups are static; you cannot decide to all of a sudden
  organize data in terms of three bytes or something! Therefore, when
  using chunky pixels, things get complicated if we decide to use a
  nonconvenient number of bits per pixel. In practice, the 8-bit
  (256-color) mode, and 24-bit (16 million color) modes are the most
  common candidates for chunky pixel displays.

     Finally, certain effects can be accomplished with the different
  systems.  Bitplanar mode is particularly useful for things like shadows
  (where an extra bitplane is set with 1s instead of 0s), and chunky mode
  is great for perspective and "mapping" (since the data for each pixel is
  localized in a single "chunk"). The latter advantage makes chunky pixel
  mode really great for games, and is what made Wolfenstein 3-D possible.

     We all know that Amigas use the bitplane system for storing images.
  However, the Macintosh and PC(VGA) both use chunky pixel modes. While
  we can optimize our RAM usage with "bizarre" modes like 8- and
  128-color, they gain the advantages of non-flicker scrolling, and the
  programming simplicity of just writing a byte where you want the pixel
  to go.

     The difference between the two modes becomes problematic in things
  like emulation. EMPLANT has a "chunky to planar" routine which it uses
  to convert a Macintosh display into an Amiga one. "Chunky to planar"
  routines are also useful for getting chunky-inclined things to run on
  Amigas (see TMAPDemo, rotdemo). On a side note, there was some
  confusion as to what EMPLANT used the MMU for with regard to chunky to
  planar. The MMU itself is incapable of performing the algorithm for the
  conversion; rather, it is used to detect what portions of the display
  memory are updated from the Mac side, and therefore the processor is
  saved from having to perform the chunky to planar conversion for the
  entire display.

     I sincerely hope that helped clear up most of the mystery concerning
  the terms "Chunky" and "Planar"!

     (Joseph Luk, [e-mail])

  5.2 What is doublebuffering?
  ============================

     Don't be ashamed if you haven't a clue as to what this is. It's
  rather simple, really. Imagine you wanted to animate something by
  drawing out each frame. Now imagine you had only one piece of paper.
  Even if you drew pretty fast, it would be difficult to see what the
  animation looks like because you'd have to erase the frame you just
  drew, in order to draw the next one!

     What if you had two pieces of paper? Why, then, you could see the
  difference between two adjacent frames. First you'd draw your first
  frame on the first piece of paper, then you'd draw the second frame on
  the other piece.  Then you'd erase the picture on the first piece of
  paper, and draw in the third frame. Then you'd erase the picture on the
  second piece of paper, and draw in the fourth frame, and so forth.

     This is the principle of doublebuffering. The computer shows you the
  picture it just drew, then turns around and draws the next one. It then
  swaps the picture in front of you with the one it just drew, and
  repeats the process. The result is a smooth animation, because you
  never need to see the computer draw; all you see is each finished
  product.

  5.3 What monitors will work on my Amiga 1200/4000?
  ==================================================

     Monitors can be classified after the horizontal scan frequency they
  require.  TVs, as well as C='s 1084 monitor, need frequencies around 15
  kHz. VGA/SVGA need approx. 30 kHz. Multisync monitors can take many
  frequencies.

     In short: You can use any monitor you want with an A1200. BUT:

     - If you use a regular VGA/SVGA monitor, you can only use a few
       display modes (like DblPAL, DblNTSC and/or Productivity). I.e.
       (320|640) x (256|512|1024) for DblPAL. This is great for Workbench
       and all "serious" utilities (DTP etc), but don't expect any games
       to work... they don't use your preferences, just take over the
       machine and assume a 15 kHz monitor. Also, you cannot utilize the
       "Early Startup Control" screen (you know, disable cache, and that
       stuff), which also requires a 15 kHz monitor. Furthermore, VGA
       monitors don't have speakers. And the VGA-type modes don't support
       Genlocks. But for a lot of "serious" work, a VGA monitor is quite
       adequate.

     - You already know what happens with a 15 kHz monitor; the
       flickering in Interlace mode. A small tip: Try to use NTSC instead
       of PAL. This increases the refresh rate from 25 Hz to 30 Hz, at
       the expense of lower vertical resolution (482 lines maximum). The
       NTSC and PAL modes aren't as bad as many people think. If your
       monitor has a lot of phosphorous (long afterglow), PAL Laced can
       be quite OK, and it gives you a resolution of 1448x566 in
       SuperHiRes. That's the highest resolution currently supported on
       AGA Amigas, in _any_ display mode.

     - A Multisync gives you the best of both worlds. The new 1940 and
       1942 monitors from C= are quite OK, although rather cumbersome to
       use... The h/v size and offset must be set manually each time you
       switch display mode.  (1)

     For a VGA/SVGA or Multisync monitor, you'd need a little shiny box
  which gives you the standard 15-pin "D" connector. It costs around $15.

     There are other alternatives... like the "AmiVGA" box ($50 or so),
  which I think is a cheapo version of the Flicker Fixer. (But it's
  really a shame to use this on an AGA Amiga.)

     Also, you can get a VGA monitor, and hook up your TV to the
  composite or RF port on the Amiga - one monitor for games, one for
  serious stuff.

     (1)  A patch is available on Aminet for Kickstart 3.0 to do this
  without manual actions in the file `os30/util/Monitor30Patch.lha'.

  5.4 How do I switch between PAL and NTSC?
  =========================================

     PAL and NTSC are two different video standards, the former being
  European, and the latter being American. PAL has a slightly taller
  screen (256 lines non-interlaced, non-overscanned) as opposed to NTSC
  (200 lines), so if you see the bottom portion of a program's screen
  getting cut off on your American machine, chances are the program was
  written for PAL, and is running on your shorter NTSC screen. PAL and
  NTSC differences are somewhat less important to European users; since
  their machines default to PAL, running an NTSC program is no more than
  a minor annoyance having the screen only appear in the top portion of
  the display.

     Therefore, for us NTSC folks, switching into PAL mode becomes
  important to avoid loss of some picture on Euro Demos, etc.

     First, the most common misconception about switching between PAL and
  NTSC is that you need a Multiscan or special monitor for such a purpose.
  Not so! Just about any monitor can handle the minor signal difference
  between PAL and NTSC (50Hz vertical refresh versus 60Hz). The 108x,
  19xx, and 20xx series, and even most TVs, can display both PAL and NTSC.
  Sometimes it is necessary to perform minor tweaking of vertical hold
  and/or v. size on your monitor to achieve full display, though this is
  trivial.

     What IS needed to switch between PAL and NTSC in software, is a
  "Fatter" (1MB) Agnus or better. If your system has more than 512K of
  CHIP RAM (use the avail command to find out) you have this chip. If you
  do not, ou can still construct a hardware switch (see below).

     The following directions assume you're an NTSC user who wants to
  switch into PAL mode, but the procedure for going from PAL to NTSC is
  much the same.

     The most common use of switching into PAL is for self-booting games,
  demos, etc.  The best way to accomplish this on pre-3.0 systems is to
  use Chris Hames' Degrader program (most recent version: 1.30). Once you
  have procured this program, the switch is as simple as selecting
  "50Hz", and "50Hz System", then installing the program's ROMTag (little
  program that runs at boot-time) by pressing the "Survive Reset(s)"
  button.

     AmigaDOS 3.0 added a PAL/NTSC switch feature to its Boot Menu, and
  all you need to do in order to access this is hold down both mouse
  buttons as the computer boots. Select Display Options, Display
  Mode/PAL, and then Boot. If the program still fails to go into PAL mode
  (Zool is one I've found), you may wish to get Degrader anyway and try
  that.

     Software PAL/NTSC switching is easy and painless. Some people have
  gone even further by installing hardware PAL/NTSC switches. This
  results in a system which even the most nasty hardware-banging programs
  can't bring to its original configuration (if it has been switched).
  The procedure is simple - most Amigas have jumpers already - but beyond
  the scope of this document.

     Therefore, if your screen is too short or cut off, seek the different
  screen mode. You'll "see new horizons", literally!

     ---------- Footnotes ----------

     (1)  PAL/NTSC switching with a MultiSync monitor is possible on 2.0+
  and easily accomplished by moving the PAL monitor type to (or NTSC, as
  applicable, I have them both in) the Devs/Monitors drawer (from the
  Storage/Monitors drawer), reboot, then go into the Prefs drawer and
  select the ScreenMode program. You will see at least two PAL modes
  available (PAL and PAL Interlaced). Simply select one of the (usually
  non-interlaced for demos) and select "Use". All windows on the Workbench
  will close, the video mode will change, and then the windows will
  reopen - that simple!

  6 Emulators
  ***********

     What? The Amiga isn't good enough? You really want it to be another
  machine?  Well, look here...

  6.1 Can I run Unix on my Amiga?
  ===============================

     Actually there are three Unix versions on the Amiga. All of them
  need at least 68030 (see 68EC0xx), probably a 68040 in the near future
  and seem to have problems with many hard-drive-controllers. You should
  have a good look into the documentation before installing it. Unix
  needs much resources, say at least 10Mb RAM and a 150Mb Unix-partition
  on the hard-drive.

    1. Commodore offered a System V Unix in the past. It contained TCP/IP,
       X11 and other software and seemed to make a good job, but it was
       expensive and after all Commodore has dropped developing it.
       Commodore-Unix needs a streamer because it is distributed on tapes.

    2. A Linux port is prepared. But actually there is not very much than
       the kernel. Specialists might like to use it, but it cannot be
       recommended for now. Linux is freely distributable. Sources:
       `ftp.tsx-11.mit.edu' or `ftp.uni-erlangen.de', both directory
       `/pub/Linux/MIRROR.tsx-11/680x0'.  Or `ftp.tu-muenchen.de',
       directory `/pub/comp/os/linux/680x0'.

    3. NetBSD is freely distributable too. Like Linux it isn't ready for
       now, but it seems to make big steps. Most GNU software is said to
       run, especially emacs and gcc. I think it's worth to have a look
       on it. Sources: `ftp.uni-erlangen.de', Directory
       `/pub/amiga/unix/NetBSD-regensburg'.  See Fish CD.

  6.2 Is it possible to use the Amiga as X11 terminal?
  ====================================================

     Yes, it is. There are two different packages available:

     GfxBase offers a commercial version which is said to be excellent,
  but expensive. The distribution includes different window managers
  andclients.  A demo version is on Aminet.
  (`gfx/x11/GfxBase-X11-Demo.lha')

     DaggeX is freely distributable and probably not finished yet. (It
  calls itself version 0.91.) Source: Aminet, `gfx/x11/DaggeX-0.91.lha'
  and `gfx/x11/twm_930531.lha'.

  6.3 Is there a way to start MS-Dos programs?
  ============================================

     PC-Task is a software only IBM-PC emulator for all Amiga computers.
  The current release is 2.03 which includes emulation of 8086 with
  MDA/CGA/EGA/VGA, serial and parallel ports, mouse, two harddrives and
  two floppies.  A demonstration version can be obtained from aminet
  sites: `/pub/aminet/misc/emu/PCTaskDemo203a.lzh'.  Chris Hames

  7 Miscellaneous
  ***************

     This last chapter contains some questions that don't fit in the
  chapters above.

  7.1 Is there any unix version of LhA?
  =====================================

     See Endings.

  7.2 What are files ending with ...?
  ===================================

     Most endings on FTP sites or Fish disks tell you that the file is
  compressed and/or is an archive containing more than one file. Some
  programs even archive whole disks. Frequently found endings and
  programs to handle the related files are:
  *.sfx*
       Compressed archives which are included in an executable program:
       Just call the program and it will extract itself (sfx = self
       extract)

  *.lha*
  *.lzh*
       Compressed archives; recommended: LhA (`util/arc/LhA_e138.run' on
       Aminet  or Fish disk 715) or Lx (`util/arc/lx100.lha' on Aminet),
       Unix version available (`misc/unix/lha-1.00.tar.Z')

  *.dms*
       Disks compressed using DMS (`util/arc/dms111.sfx' on Aminet or
       Fish disk 406)

  *.zom*
       Disks compressed using Zoom (`util/arc/Zoom_5.4.lha' on Aminet,
       Fish disk 682); an older version which you probably need for
       uncompressing PasTeX is found on Fish disk 459.

  *.zoo*
       Compressed archive; recommended: Zoo (`util/arc/zpp2-10.lzh' on
       Aminet or Fish disk 527)

  *.Z*
  *.z*
  *.gz*
       Compressed files; recommended gzip (`util/pack/gzip124x.lha' on
       Aminet), note that this are Unix files in most cases

  *.tar*
       Acrhive; recommended: tar (`util/arc/tar.lha' or
       `util/arc/gtar10.lha' on Aminet or Fish disk 445), note that tar is
       a Unix archiver and you often find soething like `.tar.Z'.

  *.arj*
       Compressed archive; recommended unarj (`util/arc/unarj-0.5.lha' on
       Aminet)

  *.zip*
       Compressed archive; recommended UnZip (`util/arc/unzip-5.1.lha' on
       Aminet), note that this are MS-Dos archives in most cases

  7.3 Is there a Stacker-like utility to pack my hard drive?
  ==========================================================

     XFH does a good job. It operates as a handler and uses the
  XPK-libraries, so you have different compression modes (NUKE is a good
  choice) and possibly even more in the future. The only disadvantage is,
  that the size of a file is limited by RAM: Don't use it with less than
  2MB of RAM.

     XPKDisk by Olaf 'Rhialto' Seibert is another stacker program that
  takes advantage of the variety of XPK libraries available. Unlike other
  harddisk compressors it does not compress the files, but creates a
  pseudo partition and stores the whole tracks as compressed files on
  your harddisk. Its major advantage is that it does not limit the
  maximum file size, because it works similar to trackdisk.device and
  therefore does not need too much temporary storage. But be careful:
  Never try to optimize an xpkdisk partition using ReOrg. It will trash
  your virtual partition.

     Another possibility is EPU. It's shareware and should offer the same
  as XFH, but without limiting the file size.

     Sources: Aminet, directory `util/pack', Fish disks 754 (XFH) and 858
  (EPU)

  7.4 Where do I get Fish disk xxx?
  =================================

     Those FTP servers have that much space (or a CD-Rom) to have all
  fish disks available online:
       ftp.isca.uiowa.edu      (USA, directory `/amiga/fx/fxxx')
       ftp.hawaii.edu          (USA, directory `/pub/amiga/fish')
       ftp.dfv.rwth-aachen.de  (Germany, directory `/pub/amiga/fish')
       ftp.funet.fi            (Finland, directory `/pub/amiga/fish')

  Note that the CD-Rom's are not always mounted. See FTP.

     Another possibility would be to ask your local dealer. :-)

  7.5 What is MUI and where do I find it?
  =======================================

     MUI is a set of shared libraries which are used to build a
  comfortable GUI (`Graphical user interface'). The general idea of MUI
  is that the programmer determines only the logical structure of the GUI
  and the look (Font, Size, Windows on Workbench, Public Screen, own
  Screen, ...) is determined by the user only. From the programmers point
  of view using MUI is simpler than `gadtools.library' but much more
  powerful. On the other hand MUI interfaces are slower than
  GadTools-Interfaces, especially on old 68000 machines.

     MUI is found in two archives, one for developers only and one for
  users. Source: Aminet, `dev/misc'.

  8 Where and how do I get software and other informations?
  *********************************************************

     Three questions arise in this context: Which programs can be found,
  where are they and how to get them and transfer them home?

  8.1 Files and databases on freely distributable software
  ========================================================

     Of course you need to know where you find things. Many good choices
  are listed in this paper, as I hope. Other sources are:

  *AmigaSciSchool*
       is a list of software and where you find it in Ascii format. It is
       posted monthly to the newsgroups `comp.sys.amiga.applications',
       `comp.unix.amiga', and `news.answers'. Additionally you will find
       it on Aminet sites (`text/doc/AmigaSciSchool-4.01'). It handles
       everything listed here and many more, for example GNU software,
       libraries (linked and shared), shells, Unix commands, educational
       and scientific software and much more.

  *FishCon*
       are lists of the Fish disk contents. (`fish/doc/fishcon-???.lzh' on
       Aminet)

  *FishXref*
       is a cross reference list of the Fish contents.
       (`fish/doc/fishxref-???.lzh' on Aminet) FishXref and Fishcon are in
       Ascii format.

  *KingFisher*
       A Fish disk database, (`fish/doc/Kingfisher1_30.lha', which is the
       program and `fish/doc/KFData850.lha' ,which contains the data, on
       Aminet or Fish disk 863) allows search by name and context. See
       Fish.

  8.2 A collection of tests
  =========================

     `Comp.sys.amiga.reviews' is a moderated newsgroup where tests of
  soft- and hardware, books and anything else relevant to the Amiga are
  posted. Its always a good idea to check this newsgroup for a review, if
  you are interested in something special. Of course you always find only
  the latest reviews, but the older postings are available per FTP from
  `math.uh.edu', Directory `/pub/Amiga/comp.sys.amiga.reviews' or on the
  Fish CDs.

  8.3 Getting files from a FTP server
  ===================================

     Things are easy for those who have access to the Internet and a
  program called FTP (File Transfer Program). Nearly all Unix computers
  have it, but not all of them allow the use of FTP.

     FTP allows you to gain access to some other machines and store and/or
  retrieve files. Normally one needs an acoount on the remote machine to
  use it, bat a number of machines have a setup that allows everybody to
  log in as the user `ftp' or `anonymous', so anybody may get files from
  them. The most important of this servers are the Aminet servers, which
  mirror each other and hence should have the same files. They are the
  best choice if you are looking for Amiga software. Aminet hosts are
       USA (MO)     ftp.wustl.edu           128.252.135.4
       USA (CA)     ftp.cdrom.com           192.153.46.2
       USA (TX)     ftp.etsu.edu            192.43.199.20
       Scandinavia  ftp.luth.se             130.240.18.2
       Germany      ftp.uni-kl.de           131.246.9.95
       Germany      ftp.uni-erlangen.de     131.188.1.43
       Germany      ftp.cs.tu-berlin.de     130.149.17.7
       Germany      ftp.uni-paderborn.de    131.234.2.32
       Germany      ftp.uni-oldenburg.de    134.106.40.9
       Germany      ftp.coli.uni-sb.de      134.96.68.11
       Switzerland  ftp.eunet.ch            146.228.10.16
       Switzerland  litamiga.epfl.ch        128.178.151.32
       UK           ftp.doc.ic.ac.uk        146.169.2.1
     All these mirrors have a directory `/pub/aminet', where you will find
  much stuff. Please use a mirror close to you! Some other important hosts
  are
       ftp.funet.fi             (Finland)
       ftp.isca.uiowa.edu       (USA)
       ftp.hawaii.edu           (USA)
       ftp.cso.uiuc.edu         (USA)
       ftp.dfv.rwth-aachen.de   (Germany)
     Note that grind, aachen and erlangen have the full collection of Fish
  disks available! See Fish disk xxx.

     To connect to a special host (ftp.uni-erlangen.de for example), you
  should type
       ftp ftp.uni-erlangen.de

  The host answers by requesting your login. You should type
       ftp

  No you are asked for a password. Please type your Email address here, if
  you have one. If not, use the password ftp.

     Now you're inside the host. There is a number of commands you may
  execute here. The most important are:
  *?*
       Prints the help text of the FTP command. Additionally you may type
       *? command* to get information on a special command.

  *bin*
       Tells the FTP program that you whish to transfer binary files. It
       is always a good choice to type bin as the very first command!
       Files you load without the bin command can be corrupt.

  *get <file>*
       Loads the given file from the host. On most Unix machines you can
       type something like `get file.txt -' or `get file.txt |more' to
       show a text on the screen. Note that there *must not* be any blank
       between the | and the word more!

  *mget <pat>*
       Loads the given files. pat may contain Unix style like wildcards.

  *put <file>*
  *mput <pat>*
       Like get and mget, but transfer files from you to the remote host.
       This is in most cases not allowed, except for a special directory
       called `incoming'. You can place files here which you want to make
       public.

  *cd <dir>*
       Like the usual cd command. The commands get, mget, put, mput, dir
       and ls refer to the current working directory.

  *dir [<dir>]*
  *ls [<dir>]*
       Like `list' and `dir' on the Amiga. Note that the FTP-dir
       corresponds to the Amiga-list!

  *bye*
       Leaves the FTP program.

     When you have used FTP for the first times you will notice, that you
  always begin with executing the same steps:
    1. Type the login (ftp in most cases)

    2. Type the password (your mail address in most cases)

    3. Enter the bin command

    4. Change the current working directory (`/pub/aminet' for example)
          This may get executed automatically. What you need is a file
  called `.netrc' in your home directory. Note that it needs to be
  protected against others! The FTP program doesn't use it, if it can be
  read by anything else than you. (Protection is set using the command
  `chmod go-rwx .netrc'.) The .netrc file contains some entries for your
  most favourite FTP sites, each separated by empy lines. A typicel entry
  may look like this:
       machine ftp.uni-erlangen.de
       login ftp
       password <your mail address> or <ftp>
       macdef init
           bin
           cd pub/aminet
     Note that on some machines it is possible to use the machine name
  `default' which meets all machines not listed in .netrc.

  8.4 Getting files from a Mail server
  ====================================

     Another way to get files is to use a mail server. This assumes that
  you can send mail to Internet addresses and get mail from Internet
  hosts. It works by sending a mail to the server specifying some
  commands, for example send commands for the files you want. Important
  mail servers are
       [e-mail]
       [e-mail]
       [e-mail]
       [e-mail]
       [e-mail]
       [e-mail]

  The most important commands are:
  *Help*
       Tells the server that you wish to get an Ascii file containing
       detailed explanation how to use the server.

  *Limit <number>*
       Specifys that you wish to get not more than <number> Kbytes per
       mail.  Larger files get splitted into small pieces of at most
       <number> Kbytes which are sent as separate mails each. Note that
       the mails may get larger because of overhead.

  *Cwd <dir>*
       Sets the current working directory to <dir>. This directory is
       used by the commands send and dir.

  *Index*
       will return a list of files and/or directories that the server
       offers. Note that this may be *very* large!

  *Index <item>*
       returns a list of files containing <item> in their names.

  *Dir [<dir>]*
       returns a list of the files and directories in the given directory.

  *Send <file1> <file2> ... <fileN>*
       Tells the server to send the given files to you.

  *Begin*
       Tells the server to ignore all lines above this command.

  *End*
       Like Begin, but specifies to ignore the lines below. (A signature
       for example!) A typical session would be to send the following
  mail to the mail server:
       BEGIN
       CD /pub/aminet/util/arc
       SEND LhA_e138.run
       END

  8.5 Getting files from a mailbox
  ================================

     You also can get files from one of the many BBS's (`Bulletin Board
  System').  Most of these are driven by private users, so there is
  nearly everywhere a mailbox which doesn't cause a too expensive
  telephone bill.

     I want to publish a list of all Amiga mailboxes here.  So please
  send to me a list of all mailboxes which are related to the Amiga - in
  any way.  I need all telephone numbers of the boxes and their name.
  Tell me the nation where the box resides and - if possible - some more
  info (Does the box have Aminet or the Fish PD or FRAS?  Is the box
  especially for Amiga users?)

     Thanks, Ignaz Kellerer

  8.6 The Fish PD series
  ======================

     A very good source is the Fish PD series. One distinguishes between
  the floppy disks and the CD-Roms.

  8.6.1 The Amiga Library disks
  -----------------------------

     Fred Fish has started in the middle eighties to collect freely
  distributable software on floppy disks. There are 1000 disks and very
  much good stuff on it.  Most Amiga dealers sell them and most magazines
  contain addresses of people mailing them to you for about 3$ per disk
  or less.  Fred Fish has terminated offering software on floppy disks.
  Instead, there is a dealer who offers the new software from the CD-Roms
  on floppy disks.

     There are some things which can be found on the Fish disks, but not
  on Aminet.  However, you can get them with FTP. See Fish disk xxx.

  8.6.2 The Fresh Fish CD-Roms
  ----------------------------

     Fred Fish is going on to offer freely distributable software. But
  now he collects it on CD-Rom's. He releases two different kinds of CD's:
    1. Monthly released disks are divided into roughly three sections:
         1. New material, which includes the material from the new
            unreleased floppy disks as well as material which does not
            appear in the floppy distribution, about 84Mb on the first
            disk.

         2. Useful utilities that can be used directly off the CD-ROM if
            desired, thus freeing up the corresponding amount of hard
            disk space (GNU Emacs, Gnu C, GNU C++, Amiga E, PasTeX,
            AmigaGuide, Installer, 2.0 and 3.0-Includes, different
            archivers, tape drivers, the AmiCDROM filesystem and many
            other GNU and BSD tools, ...), about 150Mb on the first disk.

         3. Older material from previous released floppy disks or
            CD-ROM's, about 404 Mb on the first disk. (Fish disk 600-910)

    2. Disks containing the latest software as well as recent software in
       packed format only. (These are intended to be used for example in
       BBS's.)
          I recommend especially the first kind of Fish CD's. They cost
  about 20$ plus 3$ for shipping (5$ outside USA/Canada/Mexico) and are
  available from

  8.7 How do I Read and write MS-Dos disks?
  =========================================

     No problem for owners of Workbench 2.1 or higher: The program
  CrossDos is part of the Workbench. All you have to do is mounting the
  device `pc0:' by putting it into the drawer `Devs:DOSDrivers' or by
  double-clicking the icon in `Sys:Storage/DOSDrivers'. Ms-Dos disks in
  drive `df0:' can now be handled in the usual manner replacing the word
  `df0:' by `pc0:'. For example the directory can be shown with the
  command dir pc0:.

     People still running Workbench 2.0 or lower need a program called
  `MSH'.  You will find this on the Aminet (directory misc/emu) and on
  Fish disk 382.  See Sources. After editing the file `devs:MountList' as
  described in the documentation you have to say Mount msh: in the CLI
  and can now do the same as above replacing the word `pc0:' with `msh:'.

  8.8 How do I split large files?
  ===============================

     There are some archives which are too large to fit on one disk. To
  transfer them on disks you need to split them into smaller pieces and
  transfer each part on a separate disk. I recommend Martin Schlodder's
  `Splitter'.  (Aminet, `util/misc/splitter_121.lha'. The archive
  contains binaries for MS-DOS and should be compilable without problems
  on any Unix system.

  8.9 Discussing things
  =====================

     A mailing list is a server that allows to discuss special things via
  Email. The server holds a list of people that are interested in the
  respective topic. For example, the gcc mailing list will discuss bugs,
  new features and other problems of gcc. (see Compilers) If a mail is
  sent to the server from someone he will forward this mail to all the
  other people on the list.

     You will be added to the list by sending a mail to the server which
  will usually contain the word `Subscribe' or something similar. Once you
  are no more interested in the mailing list you can unsubscribe.

     Unforunately the servers have a different syntax of subscribing and
  unsubscribing. The best way to find how to subscribe is to send a mail
  with the word `Help' to the server. He will reply a mail which should
  explain how to handle this special server.

     Some mailing lists are:
       Topic           Server

       Amok            [e-mail]
       Dice            [e-mail]         or
                       [e-mail] (Germany)
       gcc             [e-mail]
       Lisp            [e-mail]
       Mui             [e-mail]
       Oberon-A        [e-mail]

  8.10 Other FAQ's
  ================

     This is not the only FAQ, of course. Lots of FAQ's are available
  either by being posted to newsgroups or by access via FTP.

  *Amiga related books FAQ*
       This is a list of books for the Amiga, including short discussions,
       prices and sources. Newsgroups: comp.sys.amiga.misc,
       comp.sys.amiga.introduction, comp.sys.amiga.programmer (monthly)
       Ftp: rtfm.mit.edu, pub/usenet/comp.sys.amiga.misc.  Maintainer:
       Marc Atkins, [e-mail]

  *AmiTCP/IP FAQ*
       This is for users of AmiTCP/IP, a set of programs which allows to
       include an Amiga into a TCP/IP network. (Most well known nets,
       Internet for example use TCP/IP.) Newsgroups: comp.sys.amiga.misc,
       comp.sys.amiga.datacomm, comp.sys.amiga.networking (biweekly) Ftp:

       Networking seems to be quite a problem: This FAQ os for Point
       Manager, a FidoNet-client (so-called points).  Newsgroups:
       comp.sys.amiga.datacomm Ftp: rtfm.mit.edu,
       pub/usenet/comp.sys.amiga.datacomm Maintainer: Eric Krieger

  The Amiga-FAQ archive
  *********************

     The Amiga-FAQ is available in different formats: Ascii format (which
  is posted to the nets) AmigaGuide format (which is the adequate format
  on the Amiga) and in dvi format (to be printed). Additionally there is
  some stuff, that might be useful or interesting, but could not be
  included into the Amiga-FAQ:
       txt/amiga.history       On the Amiga's history
       txt/story.txt           The Commodore story (or: the Tramiel
                               story ;-)
       txt/amiga.newsgroups    Overview on comp.sys.amiga.*
       txt/amiga.sites         List of FTP sites
       txt/AmigaOverview.tex   A short overview on the Amiga-Soft- and
                               Hardware
       txt/Hardware.tips       For those people who can't live without solder
       src/JWSplit.c           The source of a file splitter
       src/JWJoin.c            The opponent to JWSplit
       src/addtoc.c            Utility to add a toc to texinfo-created docs
                               (this document uses it)

     I decided to collect these in the Amiga-FAQ archive. It is called
  AmigaFAQxxxxxx.lha (where xxxxxx is the date of the last release) and
  can be found on Aminet, directory `docs/misc'.

  Contributions
  *************

     This FAQ can neither get useful nor hit further development without
  your help. Suggestions, contributions, new answers, critics, anything
  is rather welcome.

     Please note, that very major subjects are absolutely missing yet:
  Nothing about sound, nothing on graphic cards, no Animation. These are
  some of the Amiga's best points! But I don't know them ... :-(

     So grab your keyboard (Your pencil? Well, if there's no other way...)
  and send mail to:
