Hard drive died. Got a new PC with windows 10 installed. The previous batch file routine to compile C++ code worked fine on the old machine. Now they don't work. I get the "external internal command not recognized etc. error message. I assume Win 10 comes with a C++ compiler in Visual Studio and there is a path statement in the bat file. Also I am familiar with changing the system path in the environment variables but I' :'(m not sure what goes where. Has anyone else had this problem when changing over to wWin 10
