Millions of programmers and developers worldwide have come to rely on Borland language products to develop programs ranging from simple utilities to large commercial and real-time applications. In 1989, Borland released its first object-oriented programming (OOP) language, Turbo Pascal 5.5. The release of this product stimulated much interest in the object-oriented paradigm among Pascal programmers. In May of 1990, Turbo C++ helped to bring object-oriented technology to C programmers by introducing a complete implementation of AT&T's C++ for the MS-DOS platform. In February of 1991, Borland C++ brought the power of C++ to Windows programming. And in March of 1991, Turbo Pascal for Windows gave Pascal programmers access to object-oriented programming with the new Object Windows class library. This white paper discusses what makes OOP so powerful and presents Borland's philosophy for the future growth of OOP.
