                       Section I: Development Software
                     ===================================


This is by no means a complete analysis of the tools, development systems,
etc. that are available.  This is a short list of things which *most* Mac
programmers use (or are at least aware of, and have considered using).



1.1  Compilers
--------------

Macintosh Programmer's Workshop (Apple)
---------------------------------------

MPW is a package which contains separately-purchaseable compilers for
Assembly, C, C++, and Object Pascal.  All of these run in an environment
called the MPW Shell.  The Shell is a command-line oriented environment,
designed for extreme configurability with scripts, user-writeable "tools",
i/o redirection, and lots of other bells and whistles.  On the pro side, it
can do many things that THINK cannot do; it scales much better to large
projects; it can be customized much more; and it's Apple's supported
development environment.  On the con side, it is comparatively expensive,
slow, and difficult to learn.  A debugger (SADE) is available for it, and
is philosophically similar to MPW.  An object library is available (MacApp)
which allows applications to be built on an object-oriented framework, again
similar to MPW in it's approach of being very powerful, but not necessarily
easy to learn, easy to use, small, or fast.
      
MPW is also available on the quarterly Essentials-Tools-Objects CD-ROM from
Apple.  This disc contains the latest version of the entire MPW development
environment, as well as debugging utilities and a huge collection of sample
source code.  This brings the price of the MPW environment down a bit, but
it's still much more expensive than THINK.


Think (Symantec)
----------------

Think is two separate products, Think C and Think Object Pascal.  They are
similar products.  Both are integrated editor/compiler/linker/debugger
environments.  Both come with a large library of predefined classes (the C
classes are written in a sort of pseudo C++ language that is Symantec's own
Object C, not C++).  Think Pascal is MacApp-compatable, as well.  Both
support inline assembly, but there is no separate assembler.  Their main
selling point, however, is that they are very fast and very simple.  They are
ideal for small projects that you want to finish in a few days, for
beginners, and for people who need a full-fledged development environment but
cannot afford MPW.  This is not to say that the Think environments are not
useful for commercial development; many successful commercial programs were
written with Think.  The difference in power between MPW and Think is only
noticeable with very large and/or multiple-developer projects.



1.2  Debuggers (beyond SADE and the Think debuggers)
----------------------------------------------------

MacsBug (Apple)
---------------

MacsBug is an assembly-level debugger.  It is a command-line driven, entirely
text-based environment which uses little of the Mac toolbox, and is thus
fairly stable in crashes (although it doesn't use protected memory, its main
failing in the area of stability).  It supports complex operations with
breakpoints, A-line traps, macros, expressions, and more, and can be
configured even more with user-writeable 'dcmd' external code resources.
MacsBug is free via anonymous ftp from ftp.apple.com.  It is also included
with the book "Debugging Macintosh Software with MacsBug."


TMON Professional (ICOM)
------------------------

TMON Professional is an object-level debugger which is MUCH more powerful
than MacsBug.  It has an elaborate interface which looks nothing like a Mac
application, and takes a while to get used to.  It is a very intelligent
program, however, which can often display memory in its most useful format
without help (e.g. it will disassemble code, and display a string as a
string, automatically).  It has strong support for types, allowing you to
easily view complex structures, arrays, floating point numbers, and more.
You can examine the stack, the heaps, and just about anything else you could
be interested in.  It also provides versatile scripting, and is amazingly
configurable.  There are more goodies in this package than I can possible
describe here.  Drawbacks are high price, and a very steep learning curve.


The Debugger (Jasik Designs)
----------------------------

The Debugger (also known as Jasik's Debugger, because it was written by Steve
Jasik) is the only source level debugger with all the low-level features of
Macsbug (speed, straight-forward display of important info) and many of the
advantages of source level debuggers (source code, quick display of local
variables).  Some of its best features are complete support for Object
Pascal, speed, and the ability to look at resource map and file information.
You gotta love any debugger that will display all of the low-level globals
with their values in a single keystroke!  It also has a On the down side,
the interface is an aquired taste, the documentation needs work and
distribution disks lack a certain polish.  But, phone support is very good
(you often get Steve himself).


SourceBug (Apple)
-----------------

This is similar to SADE, but I hear it is much nicer.  It is not scriptable,
however.  Perhaps someone would like to give me a review of SourceBug to put
here???



1.3  Other Tools
----------------

ResEdit (Apple)
---------------

ResEdit is the accepted tool for editing and creating resources.  It has very
little competition, partially because it is a very good and comprehensive
program, and partially because it is free (available via anonymous ftp from
ftp.apple.com).  It allows you to edit any resource in hexadecimal, and most
of the standard types have special editors that provide a direct-manipulation
paradigm for editing them.  Users may write their own pickers and editors for
custom resource types, although this is rarely done in practice.


Resorcerer (Mathemaesthetics)
------------------------------

Resorcerer is a commercially available replacement for ResEdit.  Many
developers use it exclusively, and swear by it quite vehemently.  This is
from one of them:
      
      RESORCERER is a no-holds-barred resource dynamo.
        -- embarrasses the ResEdit dialog editor
        -- supports many more template data types
        -- swap in different resource templates based on a key value
        -- creates recursive resources
        -- generates starter code for a dialog
        -- does complex searches against resource contents or titles
        -- renumbers resources in batches
        -- changes resource types
        -- excellent support from the author himself

I personally like Resorcerer for some things and ResEdit for others.  There
are certain resource types that cannot be edited with Resorcerer, like
color icons, and others that cannot be edited with ResEdit, like help
balloons.  I expect, however, that with the addition of such resource
editors to Resorcerer, I will begin to use it exclusively.

The price is the major consideration for most people.  ResEdit is free from
Apple, while Resorcerer is a commercial product (available for around $250).


Virtual User (Apple)
--------------------

Virtual User allows you to script user interactions with a program so that
they cal be relayed over and over, and it can execute scripts remotely, over
AppleTalk.  So, for instance, you could write a script that puts your program
through its paces, and then automatically execute that script simultaneously
on lots of differently configured Macintosh systems.  It is available from
APDA (#M0987LL/B).  [This paragraph taken from develop Issue 8, page 60.]


Online Companion (Addison-Wesley)
---------------------------------

Online Companion is a reference tool.  Hit a magic key combination, and a
pseudo-window opens at the bottom of the screen which allows you to type in
a full or partial name and find it in Online's database.  It contains Inside
Mac and some supplements, Tech Notes, etc.  It's fast and simple.


Think Reference (Symantec)
--------------------------

Think Reference is a reference tool.  It is a hypertext version of Inside Mac
I-V and the Tech Notes.  Click on the function or data type name to go to the
page on which it is defined.  It includes some very useful notes and examples
written by Symantec, and the function prototypes can be copied and pasted
into your editor.  Very fast and simple to use.  But beware of typos and, in
some cases, bad advice.

2.1  The Associates and Partners Programs
-----------------------------------------

From the back cover of 'develop' Issue 7:

The Associate's Program, Apple's mainstream program for commercial
developers, is a convenient and cost-effective way to get essential technical
and marketing information.  This program offers self-help technical support,
keeps you up to date with the latest products and technical documentation,
and gives you access to the Apple developer community through AppleLink.
Associates also receive discounts on equipment.  The Associates program is
designed for commercial developers and others involved in development
projects, such as contract programmers, training providers, authors, and
system integrators.

The Partners Program is open to Apple-selected commercial developers.  In
addition to receiving the same development information and tools as
Associates, Partners receive technical support via electronic mail.
Membership in the Partners program is limited to developers who directly
contribute to Apple's long-term product strategies and business objectives.

Information about becoming an Apple Associate or an Apple Partner is
available from Apple.  Call Developer Programs at (408) 974-4897, AppleLink

3.1  Books and Periodicals
--------------------------

3.1.1  Technical Books
----------------------


Inside Macintosh Volume I
   Addison-Wesley.  ISBN 0-201-17731-5.  $24.95
Inside Macintosh Volume II
   Addison-Wesley.  ISBN 0-201-17732-3.  $24.95
Inside Macintosh Volume III
   Addison-Wesley.  ISBN 0-201-17733-1.  $19.95
Inside Macintosh Volume IV
   Addison-Wesley.  ISBN 0-201-05409-4.  $24.95
Inside Macintosh Volume V
   Addison-Wesley.  ISBN 0-201-17719-6.  $26.95
Inside Macintosh Volume VI
   Addison-Wesley.  ISBN 0-201-57755-0.  $39.95

     Inside Mac is the definitive reference regarding the Macintosh toolbox.
     Volumes I and II are basically essential to any Mac programmer who uses
     the toolbox at all.  Volume III is essentially a summary, cross
     reference, index-y sort of thing, and isn't very useful.  Volume IV is
     stuff specific to the Mac Plus and later machines, which would make it
     almost as important as I and II (not many 512K Macs left out there),
     except that the routines it describes are not nearly as generally
     useful.  It does have all of the stuff on the HFS File Manager, however,
     so if you're working with File Manager routines you should definitely
     consult IV before I-III.  Otherwise, you can survive without it for a
     while.  Volume V is the Mac II volume.  It has every thing on Color
     QuickDraw, as well as lots of other goodies.  I'd say it's more useful
     than IV, but only if you're doing color.  Volume VI is the System 7
     volume.  It contains all kinds of bizarre new things which are probably
     not of general use or interest; but it contains a lot of new
     non-System-7 stuff as well (such as 32-bit Quickdraw), and it has
     corrections to the other five volumes.


Inside Macintosh X-Ref, Revised Edition
   Addison Wesley.  ISBN 0-201-57769-0.  $12.95.

     Inside Mac X-Ref is a cross-referenced index to the six volumes and
     some other Macintosh technical books.


M68000 User's Manual
   Prentice Hall.  ISBN 0-13-609249-7.  $22.95.
MC68020 User's Manual
   Prentice Hall.  ISBN 0-13-567017-9.  $22.95.
MC68030 User's Manual
   Prentice Hall.  ISBN 0-13-566423-3.  $22.95.
MC68881/MC68882 Floating-Point Coprocessor User's Manual
   Prentice Hall.  ISBN 0-13-566936-7.  $22.95.

     The Motorola references are required reading for anyone doing assembly
     programming on the Mac.  The 68000 is by far the most important.  The
     68881 manual only has relevance to those who want to do floating point
     and don't want to use SANE (the Standard Apple Numeric Environment,
     slow but robust, precise and general).


Technical Introduction to the Macintosh Family
   Addison-Wesley.  ISBN 0-201-17765-X.  $19.95.

     This book provides an overview of the general hardware design, system
     archiecture, and ROM design of the Macintosh.  It is not required for
     programming, but does provide some useful background information for
     programmers new to the Mac.


Programmer's Introduction to the Macintosh Family.
   Addison-Wesley.  ISBN 0-201-19254-3.  $22.95.

     This book provides an overview of basic Macintosh programming concepts.
     It is recommended for programmers new to the Mac.


Guide to the Macintosh Family Hardware
   Addison-Wesley.  ISBN 0-201-52405-8.  $26.95.

     This is the definitive guide to the hardware design of the Macintosh
     family.


Designing Cards and Drivers for the Macintosh Family
   Addison-Wesley.  ISBN 0-201-52404-X.  $26.95.

     This is the official guide for developers of expansion cards and
     peripheral devices for the Mac.  This book is required reading for
     anyone who wants to talk directly to expansion cards (video cards,
     for example).


Human Interface Guidelines: The Apple Desktop Interface
   Addison-Wesley.  ISBN 0-201-17753-6.  $14.95.

     This is the definitive guide to program interface design on the
     Macintosh.  When you find yourself wondering where to put the OK
     button in a dialog, consult this book.


Apple Numerics Manual
   Addison-Wesley.  ISBN 0-201-17738-2.  $29.95.

     This book describes the Standard Apple Numerics Environment (SANE),
     and provides information about the IEEE-standard arithmetic and
     about the SANE engines on the Apple IIgs and Macintosh computers.


Inside the Macintosh Communications Toolbox
   Addison-Wesley.  ISBN 0-201-57775-5.  $24.95.

     This is the definitive reference volume for the Communications Toolbox.



3.1.2  Teaching Books
---------------------


Macintosh Programming Primer (Second Edition)
   Addison-Wesley.  ISBN 0-201-60838-3.  $26.95.
Macintosh C Programming Primer Volume II
   Addison-Wesley.  ISBN 0-201-57016-5.  $24.95.

     These are excellent books for the beginning Mac programmer.  Both books
     use Think C in their examples, but developers using other platforms
     will find a plethora of useful tidbits.  I believe both books are
     available in Pascal as well.

   Hayden Books.  ISBN 0-672-48413-7.  $26.95.

     This encyclopedic collection covers the entire Mac Toolbox for the
     beginning Pascal or Assembly programmer.  It sometimes re-iterates
     Inside Mac, but always offers a fresh perspective.  Volume I covers
     basics including memory management and QuickDraw.  Volume II covers the
     other essential Toolbox managers and exemplifies each by constructing
     part of a complete text editor.  Volume III expands this application,
     covering printing, drivers, desk accessories, sound and definition
     functions.  Volume IV contains details of programming with MultiFinder,
     Color QuickDraw and styled text.


How to Write Macintosh Software (Third Edition)
   Hayden Books.  ISBN 0-201-?????-?.  ~$30.
   
     This book gives comprehensive coverage of memory management and
     debugging techniques.  It also gives an excellent overview of assembly
     language programming on the Mac.  A must-have.  Somebody please send me
     the ISBN and price of the third edition (I haven't bought mine yet).


Macintosh Programming Secrets (Second Edition)
   Addison-Wesley.  ISBN 0-201-58134-5.  $29.95.
   
     This is the second edition of Scott Knaster's classic book.  This
     edition was co-authored by Keith Rollin.  From the back cover: "If
     you've ever written Macintosh programs, or want to learn how it's done,
     this book will show you how to perform tasks that aren't explicitly
     documented in the reference books."  This is true.  Get this book if
     you want to learn how to write a tail patch, or how to hide the menu
     bar.  If you don't know what a tail patch is, that's OK; this book
     starts at (or near) the beginning.  A must-have for all beginning- and
     intermediate-level Macintosh programmers.


On Macintosh Programming: Advanced Techniques
   Addison-Wesley.  ISBN 0-201-51737-X.  $24.95.

     This book contains a lot of information on all aspects of programming
     the Mac, including hardware and software architecture, the toolbox,
     and the use of assembly, C, and Pascal for programming the toolbox.
     It includes quite a lot of source code.


Using the Macintosh Toolbox With C
   Sybex.  ISBN 0-89588-572-7.  $29.95.

     This is a fairly good book for beginning Mac programmers.  Experienced
     programmers will find nothing new here.


Programmer's Guide to MPW, Volume I
   Addison-Wesley.  ISBN 0-201-57011-4.  $26.95.

     This is a basic introduction to using MPW.  I don't recommend it for
     anyone who already uses MPW.


Programming with MacApp
   Addison-Wesley.  ISBN 0-201-09784-2.  $24.95.
C++ Programming with MacApp
   Addison-Wesley.  ISBN 0-201-57020-3.  $24.95.

     These give a basic introduction to programming with MacApp; the first
     with Object Pascal, and the second with C++.


Programming for System 7.
   Addison-Wesley.  ISBN 0-201-56770-9.  $26.95

     This is a guide to creating applications for System 7.  It describes
     the new features and functions of the operating system in detail.
     The sample code is in C and includes a complete System 7 application
     in Chapter 1 which is expanded in succeeding chapters.


ResEdit Complete
   Addison-Wesley.  ISBN 0-201-55075-X.  $29.95.

     Most of this book is not written for programmers, but includes quite
     a bit of useful information nonetheless.  It contains detailed
     discussions of using, customizing and programming ResEdit, including
     the creation of custom templates, pickers and editors. It comes with
     ResEdit 2.1 on disk, with sample source code in MPW C and Pascal.


Debugging Macintosh Software with MacsBug
   Addison-Wesley.  ISBN 0-201-57049-1.  $34.95.

     This looks like a really good and useful book, but I haven't had a
     chance to look at it yet.  MacsBug is included on disk, along with
     several examples and dcmds.


Programming the M68000
   Benjamin/Cummings.  ISBN 0-8053-5550-2.
680x0 Programming by Example

3.2  Mailing Lists
------------------

3.2.1  Comp.Sys.Mac.Programmer Digest
-------------------------------------

The Comp.Sys.Mac.Programmer Digest is a collection of article threads from
comp.sys.mac.programmer.  It is designed for people who read c.s.m.p. semi-
regularly and want an archive of the discussions.

Each issue of the digest contains one or more sets of articles (called
threads), with each set corresponding to a 'discussion' of a particular
subject.  The articles are not edited; all articles included in the digest
are in their original posted form (as received by the news server at
cs.uoregon.edu).  Article threads are not added to the digest until the last
article added to the thread is at least one month old (this is to ensure that
the thread is dead before adding it to the digest).  Article threads that
consist of only one message are generally not included in the digest.

The entire digest is available for anonymous ftp from ftp.cs.uoregon.edu
[128.223.8.8] in the directory /pub/mac/csmp-digest.  The most recent issues
are available from sumex-aim.stanford.edu [36.44.0.6] in the directory
/info-mac/digest/csmp.  If you don't have ftp capability, the sumex archive
has a mail server; send a message with the text '$MACarch help' (no quotes)
to LISTSERV@ricevm1.rice.edu for more information.

The digest is also available via email.  Just send a note saying that you
want to be on the digest mailing list to mkelly@cs.uoregon.edu, and you will
automatically receive each new issue as it is created.  Sorry, back issues
are not available through the mailing list.




3.2.2  Think Class Library Discussion
-------------------------------------

The Think Class Library discussion list is for those interested in using
Symantec's Think C and Think Pascal object-oriented class library for
Macintosh.  Discussion topics include

   * class usage, design, and implementation
   * TCL bug reports, work-arounds, and fixes
   * TCL application development techniques
   * TCL development aids

Mail to the discussion list should be sent to tcl-talk@brown.edu.
If you want to join the discussion list, mail a note saying so to
tcl-request@brown.edu.




3.2.3  MacPsych
---------------

This is a mailing list of psychologists and others interested in using the
Macintosh in research and teaching.  The intention of this service is to
provide quick and authoritative answers to questions raised by Mac-using
researchers and teachers in psychology.  Individuals who have Mac questions
to pose, or have general messages that they believe would be of interest to
research psychologists and teachers using the Macintosh, may send their
information to macpsych@stolaf.edu.  Mail sent to this address will first
pass through the moderator for the list (huff@stolaf.edu) who will forward
it to everyone on the list.

If you want to be on the mailing list, mail a note saying so to
macpsych-request@stolaf.edu.

There is an archive containing some free Macintosh software that has been
written by members of the group; for more information, write to
macpsych-request@stolaf.edu.

                          Section IV: Archive Sites
                        =============================


4.1  ftp.apple.com [130.43.2.3]
-------------------------------

Contents
   This archive contains just about everything available for free from
   Apple.  Look here first for sample source code, the latest tech
   notes, and tools such as ResEdit and MacsBug.  Very little of what
   can be found here is available from other archives.

Access
   Anonymous ftp, from inside the United States only.
   You should read the file /dts/README.FIRST before downloading from this
   archive.  Everything for the Mac is in /dts/mac.  The moderators ask that
   you download during the off-peak hours if at all possible, since this is
   just a IIci running A/UX.

Submissions
   You cannot post to this archive.


4.2  sumex-aim.stanford.edu [36.44.0.6]
---------------------------------------

Contents
   This archive contains a large collection of public-domain and shareware
   for the Mac.  It is well-maintained and updated regularly.  New
   submissions to the archive are listed every other day or so in the
   newsgroup comp.sys.mac.digest.

Access
   Anonymous ftp.  Read the files in /info-mac/help for more detailed
   information about the files in the archive.  Everything is in /info-mac.
   If you don't have ftp access you can use the mail server; send a message
   with the text '$MACarch help' (no quotes) to LISTSERV@ricevm1.rice.edu
   for more information.

Submissions
   Sumex accepts all submissions that "are of general benefit to the
   Macintosh community."  Basically, if you have something that you think is
   useful, and that other people may like to have, you should feel free to
   send it to sumex.  All submissions should be compressed and BinHexed, and
   should include a short but informative blurb at the beginning of the file.
   Mail your submissions to info-mac@sumex-aim.stanford.edu.  For more
   detailed information, consult the file

stuff available for a while, perhaps a few months, but the contents will
eventually dwindle until there is very little or nothing left.

Contents
   This archive contains most of what can be found at sumex.  Its
   emphasis is on utilities and programming-related items, but it
   contains quite a bit of other stuff as well.  It is the home of
   the comp.sys.mac.announce archives.  Many items tend to appear
   here before they show up at sumex or comp.binaries.mac.

Access
   Anonymous ftp.

Submissions
   No longer accepted.


4.4  mac.archive.umich.edu [141.211.164.153]

Contents
   I haven't explored this archive yet, but I hear it has quite a bit
   of general Macintosh freeware and shareware.

Access
   Anonymous ftp.

Submissions
   You can submit to this archive by mailing a compressed, binhexed
   file with a brief descriptive header to macgifts@mac.archive.umich.
   edu.  This address will also forward your mail to comp.binaries.mac
   and sumex-aim.stanford.edu.

4.6  ics.uci.edu [128.195.1.1]
------------------------------

Contents
   This archive has some Mac stuff, although not nearly as much as the
   major sites, such as sumex.  The main attraction is the Think C
   directory.  It contains the latest updates to Think C, as well as
   Think C related system extensions, fkeys, etc., and source code.
   Definitely worth checking out if you use Think C extensively.

Access
   Anonymous ftp.  Directory /mac.

Submissions
   Not accepted, I think.  Someone please correct me if I'm wrong.

   to the newsgroup should automatically get your file mailed to the
   moderator.  If this does not happen on your system, you can mail
   your posting to the moderator yourself at macintosh@dhw68k.cts.com,
   or at dhw68k!bytebug@ics.uci.edu if the first address doesn't work.
   Expect a delay of as much as a month before your posting shows up
   on the newsgroup.





                          =========================
                            Section V: One-liners
                          =========================


5.1  The Main Loop and Events
-----------------------------

Call MaxApplZone and MoreMasters when the application starts up.
If you call SetApplLimit, do it before calling MaxApplZone.
Use HD in MacsBug while running to estimate how many times to call MoreMasters.
Don't use SetEventMask to disable mouseUp events.  Better not to use it at all.
Call WaitNextEvent if you're running under System 6 or later.
DTS sample code passes 0x7fffffff to WaitNextEvent when nothing is happening.
DTS sample code passes GetCaretTime() to WaitNextEvent when flashing a cursor.
Call both GetNextEvent and SystemTask only if WaitNextEvent is unavailable.
Call IsDialogEvents and DialogSelect even if GetNextEvent returns false.
SetPort to a known good grafPort once every time through the event loop.
Set the cursor on suspend and resume events.
Call GetDblTime to get the maximum time for a double click.
Measure double click time from mouse up to mouse down.


5.2  Menus
----------

Use SetItem to include meta characters literally in menus.
Prepend an ASCII 0 to a menu item to use a leading '-'.
Never make MENU resources purgeable.


5.3  Resources
--------------

GetResource never produces resNotFound.  Check for a NIL handle instead.
To create a resource file, call HCreate, then HCreateResFile.
To open a resource file read-only for shared access, use HOpenResFile.
Don't leave ResLoad set to false.
GetResource on a dctb may return a non-resource copy of the dctb.


5.4  Windows, Alerts, and Dialogs
---------------------------------

Move and size windows to the bounding box of GetGrayRgn.
Hide scroll bars when deactivating a window.
Call DrawGrowIcon when activating or deactivating a window with a grow region.
DrawGrowIcon does not check to see if the window has a grow region.
Call PenNormal before calling DrawGrowIcon.
itemHit will not be set when a dialog filter is called.
Use a disabled UserItem to draw the roundrect outline around the OK button.
ModalDialog assumes the dialog is already visible and in the front.
Use screenBits.bounds to center dialogs, alerts, etc. below the menu bar.
If you save window locations in files, they may not be valid for all monitors.
DragWindow expects startPt in boundsRect; if not it may not call SelectWindow.
SelectWindow does not automatically call SetPort.  You must do that yourself.
DialogSelect responds to activate events but ignores suspend/resume events.


5.5  Drawing
------------

Always set the VisRgn and ClipRgn of offscreen ports.
Set the ClipRgn first when making a picture.
Don't make rowBytes in bitMaps greater than 8191.
To dim text, draw a rectangle with penPat=gray and penMode=patbic over it.
To draw rotated text, draw to an offscreen bitmap, rotate it, and CopyBits it.
Don't use picSize to determine the size of a picture.  Check the handle size.
Never draw outside a window except in XOR mode for temporary effects like drag.
To avoid animation flicker, synchronize drawing to the vertical retrace.
CopyBits on more than 3Kb data will work, but it might have to allocate memory.
The small Mac screen is 512 pixels wide by 342 pixels high including menu bar.


5.6  Files
----------

Don't write in the application file.  This will fail with read-only devices.
Use PBGetVInfo to convert a VRefNum to a volume name.
Delete uses the Poor Man's Search Path, so don't delete blindly.
File Manager routines with dirID=0 use the Poor Man's Search Path.
Truncate and reallocate files before overwriting to reduce fragmentation.
Check/change the creator and type of Save As... files before overwriting.
If you rewrite files by deleting and creating, copy all Finder information.
Directory ID's are longs, not shorts.  Shorts work ALMOST all the time.
Always set the version number that appears in some file manager calls to 0.
To convert a pathRefNum to a name or file number, use PBGetFCBInfo.
Prevent the creation of files with names that begin with a period.


5.7  Interrupts and VBL Tasks
-----------------------------

Don't call any Memory Manager routines during an interrupt.
Unlocked handles may not be valid during an interrupt.
To synchronize to the vertical retrace on Macs with slots use SlotVInstall.


5.8  Handles and Pointers
-------------------------

Lock handles before passing their dereferenced pointers to any routine.
Lock handles before setting referenced data to expressions containing functions
Put an odd long at location zero on a 68000 to help find NIL handle references.
Use HGetState/HLock/HSetState to lock a handle then put it back as it was.


5.9  General

Always use unsigned characters within text and Pascal-format strings.
Save application preferences in a folder named Preferences in the System Folder
Use SysEnvirons to find the System (Blessed) Folder.
Use GetAppParms to get the name of the application.
The high bit of SysParam . volClik enables the alarm clock.
Check the application name at $910 before exiting with ES within MacsBug.
To exit to shell in the mini-debugger, enter SM 0 A9 F4 and then G 0.
In Pascal, don't nest procedures to be passed by procedure pointer.
In Pascal, "with theHandle^^" is unsafe if memory compaction can occur.
