Why doesn't the Mac do preemptive multitasking? ============================================================================= =================================== 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. ======================================== Section II: Apple Developer Programs ======================================== 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 DEVHOTLINE (devhotline@applelink.apple.com), or write 20525 Mariani Avenue M/S 75-2C Cupertino, CA 95014, for information or an application for the Associates or Partners program. Developers outside the U.S. and Canada should instead contact the Apple office in their country for information about developer programs. 2.2 Apple Developer University ------------------------------- From the back cover of 'develop' Issue 7: Apple Developer University provides training for all levels of Macintosh programmers. The hands-on classes give you experience using the most up- to-date development tools. Classes are offered in locations across the United States, and on-site instruction can also be arranged. Multimedia self-paced courses are available from Developer University through APDA. These courses include Macintosh Programming Fundamentals, User-Centered Design, and Introduction to Object-Oriented Programming. The registrar at (408) 974-6215 can reserve your place or send a current catalog. You can also AppleLink DEVUNIV (devuniv@applelink.apple.com) or write 20525 Mariani Avenue M/S 75-6U Cupertino, CA 95014 2.3 APDA --------- From the back cover of 'develop' Issue 7: The Apple Programmers and Developers Association (APDA) offers convenient worldwide access to development tools, resources, training products, and information for anyone interested in developing applications on Apple platforms. A quarterly APDA catalog features over 300 technical products from Apple and third-party developers. There are no membership fees. APDA offers convenient payment and shipping options, including site licensing. Apple Associates or Partners automatically receive the APDA catalog. To order products or to receive a complimentary catalog, (800) 282-2732 U.S. (800) 637-0029 Canada (408) 562-3910 International (408) 562-3971 Fax 171-576 Telex APDA AppleLink (apda@applelink.apple.com) 20525 Mariani Avenue M/S 33-G Cupertino, CA 95014 2.4 Developer CDs ------------------ The developer CDs are available quarterly from APDA, or monthly to Apple Associates and Partners. The quarterly version is also included in the quarterly issue of d e v e l o p. They contain just about everything that Apple makes freely available, including SpInside Mac, the Tech Notes, and a plethora of code snippets. ======================================= Section III: Sources of Information ======================================= 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.

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. Macintosh Revealed, Volume One: Unlocking the Toolbox Hayden Books. ISBN 0-8104-6551-5. $26.95. Macintosh Revealed, Volume Two: Programming with the Toolbox Hayden Books. ISBN 0-8104-6561-2. $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.

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. 3.3 Miscellaneous ------------------ 3.3.1 Usenet Mac Programmer's Guide ------------------------------------ The Usenet Mac Programmer's Guide (UMPG) is a collection of useful tips culled from comp.sys.mac.programmer. Compiled by Matthew X. Mora (mxmora@unix.sri.com), it is organized by topic and includes a table of contents and index. It is available via anonymous ftp from sumex-aim. stanford.edu (36.44.0.6) in the directory /info-mac/tech/. It is also available in a pre-printed version, or on disk.

Some of the questions that it answers are asked occasionally on comp.sys.mac.programmer. Please read this FAQ list before posting to c.s.m.p. It is available from the sumex archives and its mirror sites (see section 4.2) in the file /info-mac/ report/csmf-faq.txt. ============================= 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 /info-mac/help/posting-guidelines.txt. 4.3 rascal.ics.utexas.edu [128.83.138.20] ------------------------------------------ This archive is being discontinued as of 5/92. It will continue to have 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. 4.5 ftp.cs.uoregon.edu [128.223.8.8] ------------------------------------- Contents This is the home of this FAQ list, as well as the Comp.Sys.Mac. Programmer Digests. There's also a little sample code not included in the FAQ. Access Anonymous ftp. Directory /pub/mac. Submissions Not accepted. 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. 4.7 ftp.brown.edu [128.148.176.55] ----------------------------------- Contents This is the home of the Think Class Library mailing list. It includes TCL bug fixes and new classes, as well as an archive of the tcl-talk mailing list. Access Anonymous ftp. Directory /pub/tcl. Submissions Submissions to the archive should be mailed to tcl-request@brown.edu or placed in the directory /incoming/tcl with accompanying mail to tcl-request. Encode all submissions in BinHex 4.0 format and include a descriptive header. Please do not redistribute Symantec's TCL source. 4.8 comp.binaries.mac [newsgroup] ---------------------------------- Contents This is a moderated newsgroup for distribution of Macintosh freeware and shareware. Just about everything that gets sent to sumex and the other major archives gets sent here as well. Access Subscribe to the newsgroup.... Submissions All files should be compressed and binhexed for mailing. Posting 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. ============================== Credits / Acknowledgements ============================== Many thanks to Ben Haller, who started this whole thing, and did quite a lot of work on this posting before handing it off to me.
