C/C++ compilers have long been available for various processors and operating systems. Some compilers are very old, but maintained and up to date. Others are simply old compilers. So it was time to launch a new modern compiler, one that has been created with the latest programming methods and can do everything from the beginning that was cumbersomely added to the old compilers. Is it just a new compiler? Then it is uninteresting and boring. If it also includes code analysis tools and other tools for improving code quality, it is unrivalled in its value. For OS-9 a new compiler with the latest C/C++ standards is needed.
