Document System Calls
Office on the Mac uses many proprietary calls to dylib libraries that duplicate Windows System libraries. Office for Mac programmers could expand the range of services to macOS clients if Microsoft would document these libraries. Please hire a couple of competent people to make this possible.

Microsoft - please provide better documentation of your dylib libraries!

Is Office open-sourced or not? Open it up, if you want (or need) participation for the programming community.
