Increases the reliability of applications. Facilitates the creation of reusable code. Offers a better model forbuilding applications than procedural programming can provide. � Based on AT&T Provides data abstraction, multiple inheritance, Release 2.0 C++ and message-passing capabilities. Offers operatoroverloading and protected variables within classes. Provides strong type-checking forC-based applications. Extensions for the Supplies full access to the Macintosh Toolbox Macintosh environment and operating system. Supports Object Pascal functions and procedures, forcompatibility with MacApp. Provides access to SANE fornumerical accuracy. Supports SADE forsource-level debugging.
