As well as being the element with 6 protons and 6 (or rarely 8) neutrons, Carbon is also a set of APIs for MacOSX. Programs written for Carbon can also run on MacOS9? or 8.6 with a library called CarbonLib?. Earlier versions of CarbonLib? also run on PowerPC computers running MacOS 8.1. Carbon consists of the 75% of the API calls of Classic? MacOS (which accounted for 95% of what programs used). The API calls that wouldn't work with ProtectedMemory or PreEmptiveMultitasking? were removed. Carbon applications are usually written in C or C++.
