There is a problem with pictures that contain PostScript code. Sometimes the PostScript code  that is inserted into the picture is dependent on the position of the  picture on the page. The problem arises when these pictures are cut or  copied from their original position, and pasted into another position or  even into another document. The PostScript code will not know the new  location of the picture, and will not execute correctly.
Plotting Small Icons     MacTNsDL         Trilogy III:Files:MacTechNotes:Imaging:Graphics:Plotting Small Icons                      0       8K     10/29/92     Plotting Small Icons - This Technical Note discusses the 'SICN' resource  format and how to plot one in a GrafPort.

The Pascal glue code, C glue  code, and the assembler equates and macros for the calls are included in  this note. Changes since October 1991. Corrected ioObjType input values for PBGetUGEntry.
PBHSetVol            MacTNsDL         Trilogy III:Files:MacTechNotes:Files:PBHSetVol                      0       5K     10/29/92     PBHSetVol - This note explains PBHSetVol, and why its use is not  recommended. PBHSetVol, like SetVol and PBSetVol, allows you to set the  current default volume and directory to be used with subsequent File  Manager calls. Unlike SetVol and PBSetVol, though, PBHSetVol lets you  specify the volume and the directory separately, using the ioVRefNum and  ioWDDirID fields.
PBGetCatInfo&ioFDirIndex     MacTNsDL         Trilogy III:Files:MacTechNotes:Files:PBGetCatInfo&ioFDirIndex                      0       8K     10/29/92     PBGetCatInfo&ioFDirIndex - This technical note describes how to set  ioFDirIndex for PBGetCatInfo. The File Manager chapter of Inside Macintosh  volume IV is not very specific in describing how to use ioFDirIndex when  calling PBGetCatInfo. It correctly says that ioFDirIndex should be positive if you are making indexed calls to PBGetCatInfo (analogous to making  indexed calls to PBGetVInfo as described in Technical Note #24).
PBClose the Barn Door     MacTNsDL         Trilogy III:Files:MacTechNotes:Devices:PBClose the Barn Door                      0       5K     10/29/92     PBClose the Barn Door - This Technical Note discusses the need for  Macintosh device drivers to implement _PBClose. You may get the idea when  implementing device drivers that _PBClose is superfluous.  After all, if  you have a resident driver for a NuBus™ video board, the only time your  driver is not needed is if the operating system is going away.  It might  seem that nothing important can happen after the operating system goes  away, so why bother with _PBClose?  Well, it turns out a lot can happen,  and this Note tells you why it is important to implement a Close (_PBClose) routine.

Changes since April 1990. Clarified the section on window updates with  off-screen bitmaps to explicitly limit these updates to your own windows.
Object Pascal        MacTNsDL         Trilogy III:Files:MacTechNotes:Platforms & Tools:Object Pascal                      0       5K     10/29/92     Object Pascal - Object Pascal must have a CODE segment named %_MethTables  in order to access object methods. In MacApp this is taken care of “behind  the scenes” so you don’t have to worry about it . However, if you are doing a straight Object Pascal program, you must make sure that %_MethTables is  around when you need it. If it’s unloaded when you call a method, your  Macintosh will begin executing wild noncode and die a gruesome and horrible death.
Number of Resources     MacTNsDL         Trilogy III:Files:MacTechNotes:Toolbox:Number of Resources                      0       4K     10/29/92     Number of Resources - This note describes the limitation of the number of  resources in a single resource file.

NuBus Interrupt Latency     MacTNsDL         Trilogy III:Files:MacTechNotes:Hardware:NuBus Interrupt Latency                      0       8K     10/29/92     NuBus Interrupt Latency - This Technical Note discusses NuBus™ interrupt  latency, and why, contrary to popular belief, the Macintosh is not a  real-time machine. Changes since December 1988. Changed sample code to  defer cursor rendering to a deferred task rather than a “pseudo-VBL” task. The Macintosh is not a real-time machine.  The Macintosh does not support  DMA. There are many variables in the Macintosh that make it impossible to  deterministically figure out exactly when things are going to happen.   Despite these facts, there are those who must push the envelope. For these  courageous adventurers, we provide the following information in the hope  that it speeds your journey.
NuBus Block Transfers     MacTNsDL         Trilogy III:Files:MacTechNotes:Hardware:NuBus Block Transfers                      0       9K     10/29/92     NuBus Block Transfers - This Technical Note describes the sResource entries needed in a declaration ROM to inform NuBus™ masters when a board is  capable of receiving or sending block transfers. In addition to normal long word transfers, the NuBus specification defines a number of block transfer  transactions. In block mode transfers, the system arbitrates for the bus a  single time and then performs a group of consecutive long word transfers  before releasing the bus. The reduction in bus arbitration time can result  in considerable gains in performance.
Notification Manager     MacTNsDL         Trilogy III:Files:MacTechNotes:Toolbox:Notification Manager                      0       8K     10/29/92     Notification Manager - This Technical Note describes the Notification  Manager, the part of the operating system that lets an application, desk  accessory, or driver alert the user.

MoveHHi and SetResPurge     MacTNsDL         Trilogy III:Files:MacTechNotes:Memory:MoveHHi and SetResPurge                      0       4K     10/29/92     MoveHHi and SetResPurge - SetResPurge(TRUE) is called to make the Memory  Manager call the Resource Manager before purging a block specified by a  handle. If the handle is a handle to a resource, and its resChanged bit is  set, the resource data will be written out (using WriteResource). When  MoveHHi is called, even though the handle’s block is not actually being  purged, the resource data specified by the handle will be written out. An  application can prevent this by calling SetResPurge(FALSE) before calling  MoveHHi (and then calling SetResPurge(TRUE) after the MoveHHi call).
Movable Modal Dialogs     MacTNsDL         Trilogy III:Files:MacTechNotes:Toolbox:Movable Modal Dialogs                      0       6K     10/29/92     Movable Modal Dialogs - This Technical Note describes the process by which  an application can remap the Help Manager 'hmnu' resource while a movable  modal dialog box is on the screen.

The number of master pointers that a program needs can be determined  empirically. MoreMasters can be tricked into creating the exact number of  master pointers desired.
Mixing HFS and C I/O     MacTNsDL         Trilogy III:Files:MacTechNotes:Files:Mixing HFS and C I/O                      0       7K     10/29/92     Mixing HFS and C I/O - This Technical Note discusses the problem of mixing  calls to the Macintosh file system with calls to MPW C library file I/O  routines. Problems with Communication Between HFS and C. Frequently,  developers want to use both Macintosh file I/O and C file I/O.  Developers  who do this must keep in mind that they are combining two distinct file  representations (the Macintosh and ANSI C). The only limitation on mixing  HFS and C I/O functions is that they cannot be mixed on the same open file. There are three reasons why this cannot be done.

Low-Level Printing     MacTNsDL         Trilogy III:Files:MacTechNotes:Imaging:Printing:Low-Level Printing                      0       4K     10/29/92     Low-Level Printing - When you use the low-level printer driver to print,  you don’t get the benefits of the error checking that is done when you use  the high-level Printing Manager. So, if the user prints to an AppleTalk  ImageWriter (including an AppleTalk ImageWriter LQ) that is busy printing  another job, the driver doesn’t know whether the printer is busy, offline,  or disconnected.  Because of this, PrError will return (and PrintErr will  contain) abortErr.
Lock, Unlock the Range     MacTNsDL         Trilogy III:Files:MacTechNotes:Files:Lock, Unlock the Range                      0       7K     10/29/92     Lock, Unlock the Range - This Technical Note discusses the _PBLockRange and _PBUnlockRange routines; how they act on local and shared volumes and why  you should not set the ioPosMode field to fsFromLEOF in the parameter block for those routines when accessing a file on an AppleShare volume. Changes  since April 1988. Added information on how _PBLockRange and _PBUnlockRange  really work.

KillNBP              MacTNsDL         Trilogy III:Files:MacTechNotes:Networking:KillNBP                      0       4K     10/29/92     KillNBP - This technical note clears up some confusion regarding the Name  Binding Protocol KillNBP function. The description of the PKillNBP function on page 519 of Inside Macintosh Volume V is somewhat confusing. The data  type of the parameter thePBptr is incorrectly given as ATPPBPtr and the  pointer to the queue element from the NBP call to be aborted is incorrectly given as being passed in aKillQEl.
Keybd Resource Q&As     MacTNsDL         Trilogy III:Files:MacTechNotes:Text:Keybd Resource Q&As                      0       8K     10/29/92     Keybd Resource Q&As - This Technical Note contains a collection of Q&As  relating to a specific topic—questions you’ve sent the Developer Support  Center (DSC) along with answers from the DSC engineers.

This Note also  provides a “safe” method for remapping keyboards. Changes since October  1990. Added a section on how 'KMAP' resources are matched to specific ADB  keyboard types and a section on the original Macintosh and Macintosh Plus  keyboards.
Joy of 32-Bit Clean     MacTNsDL         Trilogy III:Files:MacTechNotes:Overview:Joy of 32-Bit Clean                      0       9K     10/29/92     Joy of 32-Bit Clean - What to do (and what not to do) to make your programs run under A/UX and future versions of the Macintosh System Software. Changes since October 1988:  Added information on writing 32-bit clean  CDEFs, and updated A/UX information to reflect the capabilities of A/UX  1.1.
ioPosOffset          MacTNsDL         Trilogy III:Files:MacTechNotes:Files:ioPosOffset                      0       4K     10/29/92     ioPosOffset - The Device Manager chapter of Inside Macintosh Volume II says that ioPosOffset is passed to and returned by Read and Write calls. It also says that “After the read [or write] is completed, the position is returned in ioPosOffset…” Actually, ioPosOffset is not changed by either call. Also  note that device drivers should only look at the dCtlPosition field of the  DCE, and should not look directly at the ioPosOffset field of the parameter block. The Device Manager sets up dCtlPosition for the driver, taking into  account both the ioPosMode and the ioPosOffset.
ioNamePtr            MacTNsDL         Trilogy III:Files:MacTechNotes:Files:ioNamePtr                      0       4K     10/29/92     ioNamePtr - It is very important to set ioNamePtr when making PB calls,  even if you don’t want  those calls to return a name. Whenever Inside  Macintosh indicates that ioNamePtr is either required for input or returns  something, you must set ioNamePtr to either nil (if you aren’t using a  name) or to point to storage for a Str255. If you don’t explicitly set  ioNamePtr, strange and unusual crashes may occur, depending on the  machine/configuration your code is run on.

Inside Object Pascal     MacTNsDL         Trilogy III:Files:MacTechNotes:Platforms & Tools:Inside Object Pascal                      0       5K     10/29/92     Inside Object Pascal - This Technical Note briefly explains why Object  Pascal and MacApp should only be used to write applications and MPW tools. Although Pascal can be used to write desk accessories, drivers, XCMDs and  other types of stand–alone code, and Object Pascal is an extension of  Pascal, Object Pascal cannot be used to write anything other than an  application.  This limitation is due to the fact that Object Pascal method  dispatching relies on a valid A5 pointing to a jump table.  Because MacApp  is written in Object Pascal, this limitation applies to it as well.
Image Writer IIMotio     MacTNsDL         Trilogy III:Files:MacTechNotes:Imaging:Printing:Image Writer IIMotio                      0       5K     10/29/92     Image Writer II Motion - The purpose of this technical note is to answer  the many questions asked about why the paper moves the way it does on the  ImageWriter II.

Applications should strive to be compatible across all  Macintoshes, but there are times when an application must have knowledge  about the machine that it is running on.  The new trap, SysEnvirons, will  give an application most of the information that it requires (what  hardware, what version of system software…).
Icon Drawing in 7     MacTNsDL         Trilogy III:Files:MacTechNotes:Imaging:Graphics:Icon Drawing in 7                      0      15K     10/29/92     Icon Drawing in 7 - This Technical Note describes how to utilize the  built-in System 7 icon drawing utility. Use this information to better  conform to the System 7 visual human interface. Changes since May 1992. In  this Note, we replaced the C and Pascal interface files and corrected the  related text. So much text was tweaked that change bars are used only on  code changes.

Generally,  if a Macintosh has problems with a High Sierra disc, it’s because the disc  in question  doesn’t really conform to the High Sierra specification.
IOP Diffs Under A/UX     MacTNsDL         Trilogy III:Files:MacTechNotes:Platforms & Tools:IOP Diffs Under A/UX                      0       6K     10/29/92     IOP Diffs Under A/UX - This Technical Note discusses use of the Macintosh  IIfx IOP-based serial driver under A/UX, especially under certain error  conditions which cause it to perform differently than documented in  termio(7).  (The SCC driver, used on non-IOP machines, conforms to  termio(7) in all cases.)  References to “the driver” herein refer to the  IOP-based serial driver, seriop.c.
HyperCard and You     MacTNsDL         Trilogy III:Files:MacTechNotes:Platforms & Tools:HyperCard and You                      0      14K     10/29/92     HyperCard and You - This Technical Note describes some HyperCard anomalies  with which developers should be familiar when developing stackware, and it  documents differences between HyperCard versions where appropriate.

Hard Disk Hacking     MacTNsDL         Trilogy III:Files:MacTechNotes:Devices:Hard Disk Hacking                      0       5K     10/29/92     Hard Disk Hacking - For those of a technical bent with some extra time, you can build your own hard disk system from a cheap SCSI drive and a driver  that you write. This is not a project for those short on time, so beware.
Handles vs. Pointers     MacTNsDL         Trilogy III:Files:MacTechNotes:Memory:Handles vs. Pointers                      0       5K     10/29/92     Handles vs. Pointers - A handle is a handle and a pointer is a pointer.  Applications should avoid embedding non-relocatable objects (that the  system assumes will never move) in handles. In order to avoid  fragmentation, some applications embed pointers (non-relocatable memory  manager objects) in handles, so that the handles can be moved around as  needed. This can cause several problems, especially with the Macintosh II,  and should be avoided.
HFS Tidbits          MacTNsDL         Trilogy III:Files:MacTechNotes:Files:HFS Tidbits                      0       5K     10/29/92     HFS Tidbits - This Technical Note describes two poorly documented features  of the File Manager.
HFS Ruminations      MacTNsDL         Trilogy III:Files:MacTechNotes:Files:HFS Ruminations                      0      10K     10/29/92     HFS Ruminations - This technical note contains some thoughts concerning  HFS.

HFS Comaptibility     MacTNsDL         Trilogy III:Files:MacTechNotes:Files:HFS Comaptibility                      0       7K     10/29/92     HFS Comaptibility - This technical note tells you how to make sure that  your applications run under the Hierarchical File System (HFS). The  Hierarchical File System (HFS) provides fast, efficient management of  larger volumes than the original Macintosh File System (MFS). Since HFS is  hierarchical, HFS folders have a meaning different from MFS folders. In  MFS, a folder has only graphical significance—it is only used by the Finder as a means of visually grouping files. The MFS directory structure is  actually flat (all files are at the ‘root’ level). Under HFS, a folder is a directory that can contain files and other directories.
Getting thru CUSToms     MacTNsDL         Trilogy III:Files:MacTechNotes:Platforms & Tools:Getting thru CUSToms                      0      15K     10/29/92     Getting thru CUSToms - This technical note provides a way for developers to allow sophisticated users to add code to an off-the-shelf application.   Using this scheme, the user can easily install the code module; the  application has to know how to call it and, optionally, be able to respond  to a set of predefined calls from the custom package.
Getting a Full Pathname     MacTNsDL         Trilogy III:Files:MacTechNotes:Files:Getting a Full Pathname                      0       8K     10/29/92     Getting a Full Pathname - This Technical Note describes how to generate a  full pathname, given either a Working Directory ID or a real vRefNum and a  DirID. By using the techniques shown in this Note, you can find the full  pathname from information such as that returned by Standard File. Changes  since June 89. Added a note on how to check for A/UX. Fixed bug in C  version:  BlockMove() parameters were reversed in pStrcpy(); added range  checking to pStrCat(); changed references from “longint” to “long”.  Fixed  bug in Pascal and C versions. Changed fsRtDir to fsRtdirID and made  references to gHaveAUX consistent.

Fun with PrJobMerge (#2)     MacTNsDL         Trilogy III:Files:MacTechNotes:Imaging:Printing:Fun with PrJobMerge (#2)                      0       6K     10/29/92     Fun with PrJobMerge (#2) - This Technical Note discusses some interesting  behavior you’ll encounter while using PrJobMerge with the 7.0 and 7.1  versions of the LaserWriter driver. Changes since March 1992. Corrected the Vulcan-like “THPring” typo to correctly read “THPrint,” and changed a  comment in the code to mean what I originally meant.
Forcing Floppy Size     MacTNsDL         Trilogy III:Files:MacTechNotes:Devices:Forcing Floppy Size                      0       5K     10/29/92     Forcing Floppy Size - This document explains how to initialize a disk as  either single- or double- sided. It only applies to 800K drives, of course. You can call the disk driver to initialize a disk and determine  programmatically whether it should be initialized as single- (MFS) or  double- (HFS) sided. All you have to do is call the .Sony driver directly  to do the formatting then the Disk Initialization Package to write the  directory information.
Fonts and the Script Mgr     MacTNsDL         Trilogy III:Files:MacTechNotes:Text:Fonts and the Script Mgr                      0       9K     10/29/92     Fonts and the Script Mgr - This Technical Note describes how the Script  Manager uses the font family ID to determine a script code.
Font Names           MacTNsDL         Trilogy III:Files:MacTechNotes:Imaging:Fonts:Font Names                      0       8K     10/29/92     Font Names - This note recommends the use of font names rather than font  numbers. The Font Manager chapter of Inside Macintosh Volume IV claims that font family numbers 0 through 127 are reserved for use by Apple, and  numbers 128 through 255 are assigned by Apple for fonts created by software developers. This is no longer true. Developer Technical Support does not  assign font family numbers. You should only use font numbers to reference  the system font (font 0) and application default font (font 1). All other  fonts should be identified by name. The Font/DA Mover will renumber a font  when moving it into a file containing a conflicting font family.
Font Mgr Q&As        MacTNsDL         Trilogy III:Files:MacTechNotes:Text:Font Mgr Q&As                      0      15K     10/29/92     Font Mgr Q&As - This Technical Note contains a collection of Q&As relating  to a specific topic—questions you’ve sent the Developer Support Center  (DSC) along with answers from the DSC engineers.

Font File Icons      MacTNsDL         Trilogy III:Files:MacTechNotes:Imaging:Fonts:Font File Icons                      0       5K     10/29/92     Font File Icons - This Technical Note discusses why you should not link  directly from your font files to the font icons provided by LaserWriter  driver 5.2 and later. Changes since December 1988. Added some useful tips  and described the method required to bundle an icon to your font file.
Font Family Numbers     MacTNsDL         Trilogy III:Files:MacTechNotes:Imaging:Fonts:Font Family Numbers                      0       9K     10/29/92     Font Family Numbers - This Technical Note discusses the range of numbers  available for identifying font families, how they are allocated among  script systems, and what numbers should be used for fonts that were  designed to be used as a tool in an application. Changes since August 1990. Apple Computer no longer registers font family ID numbers; this note has  been altered to reflect the change in policy. Also, the relationship of  outline fonts to font families is discussed briefly.
Fond of FONDs        MacTNsDL         Trilogy III:Files:MacTechNotes:Text:Fond of FONDs                      0      25K     10/29/92     Fond of FONDs - This Technical Note takes the place of Tech Note #26,  “Character vs. String Operations in QuickDraw” by Bryan Stearns (March  1988), which pointed out the possible differences between the results of a  StringWidth call and successive calls to CharWidth. This Note updates and  brings into a broader context the issues related to text measuring. It also provides additional documentation on font family resources ('FOND's), and  addresses various other frequently asked questions related to the Font  Manager.
Floppy Disk Int Q&As     MacTNsDL         Trilogy III:Files:MacTechNotes:Hardware:Floppy Disk Int Q&As                      0       5K     10/29/92     Floppy Disk Int Q&As - This Technical Note contains a collection of Q&As  relating to a specific topic—questions you’ve sent the Developer Support  Center (DSC) along with answers from the DSC engineers.

Don’t Call ADBReInit in sys     MacTNsDL         Trilogy III:Files:MacTechNotes:Hardware:Don’t Call ADBReInit in sys                      0       5K     10/29/92     Don’t Call ADBReInit in sys - Because of a bug (which causes auto-repeat)  in the ROM version of the Macintosh SE keyboard driver, a patch was placed  in System 4.1. If ADBReInit is called, the ROM version of the keyboard  driver will be reloaded, and the RAM version of the driver with the patches will not be used. Therefore, it is recommended that ADBReInit not be called on the Macintosh SE until the problem is fixed. (There is no need to call  ADBReInit.) This problem will not occur with the Macintosh II ROM version  of the keyboard driver.
