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.

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…
