All rights reserved. MPW3.2 Release Notes This release note summarizes the differences between MPW 3.2 and MPW 3.0, the last version for which a reference manual exists. Details beyond those given in this note are to be found in separate release notes entitled MPW 3.2 Shell, MPW 3.2 Object Pascal, MPW 3.2 C, MPW 3.2 Assembler, MPW 3.2 Libraries & Interfaces, MPW 3.2 "411" Help, MPW 3.2 Run-Time Architecture, MPW 3.2 SIOW, and MPW 3.2 Tools & Scripts. Three of the above: "411" Help, Run-Time Architecture, and SIOW describe completely new features. Principal Changes Shell • Projector has a number of enhancements. • The Editor provides split windows. • A marker browser has been provided. • There are additional commands for the faccess function. • The save command, when scripted, saves the resource fork of a file if any resource has changed. • MPW can now be run under A/UX. • New System 7 .0 error codes have been added to the file SysErrs.err. c • A variety of new object code optimizations have been implemented. • There are new compiler options to control optimization level. MPW3.2 Release Notes 1 Copyright Apple Computer, Inc. 1990-1991. All rights reserved. • Support is provided for the MacApp debugger and code profilers (generating a preamble and postamble for functions). • A new pragma is provided for passing parameters to functions via registers. • A new pragma is provided to force the generation of MC68020 code. • A new pragma is provided to prevent the multiple inclusion of header files. • There is a new option for invoking the "32-bit everything'' run-time architecture. • A new pragma is provided to prevent dead code stripping by the linker. • An option is provided for machines having the MC68020 and up that allows stand-alone code segments greater than 32K. Object Pascal • Further object code optimizations, including an optional two-pass code generation phase which allocates unused scratch registers for local data. • An option to control optimization level. • An option for invoking the "32-bit everything'' run-time architecture. • A new syntax for declaring forward and external objects • Enhancements to the Object Pascal declaration handling to support MacApp. • Support for USES clauses in the implementation section of a unit. • Support for external C functions with arbitrary numbers of arguments,. • The ability to omit static links for nested procedures that don't need them. • Increase in the number of nested include files, the maximum number of nested compiletime conditionals, and in the number of long identifiers. ASM • New optimizations. • Longer identifiers to support C++ name mangling. • MC68040 s…

This release note, the MPW 3.0 ERS' s, and other tool-specific release notes are the documentation for this release. Differences between the ERS, previous 3.0 development releases, and this release are documented below. If no release note exists for something that has an ERS, assume that the piece has been implemented as documented in the ERS. MPW 3.0A2 highlights include a symbolic debugger, project management system, and new C compiler. All of the C pieces of MPW, were compiled with this new C. Since MPW 2.0, the C header files have three important changes: every function has a function prototype, the capitalization for routines that pass strings and points has changed, and the definition of Str255 has changed. The capitalization and Str255 changes will require changes to your C source. See the section below titled ''Interfaces." ( Another change in MPW 3.0A2 may require a change to your Makefiles. The Pascal compiler no longer uses the Load/Dump mechanism. Instead, the compiled object code for each unit is saved in the unit's resource fork. Therefore, dependency rules (in Makefiles) upon Pascal dump files are obsolete. See the section below titled "Pascal." The A2 C compiler now has function prototype checking turned on. Furthermore, the C compiler is very strict about type compatibility. Be forewarned ... Installation • Installation from floppies - MPW 3.0 now includes an installer disk for installing MPW from a set of floppy disks .. Here are the steps for automatically installing MPW on your disk: 1) drag the ''Installation Folder" onto the hard disk where you want MPWinstalled · 2) launch the MPW Shell found in the ''Installation Folder" App…
