We bought the Keil C51 software package back in 2002 but we never used it to develop any code. So when I recently created a new project using this Keil software I see that Target 1 and Source Group 1 is created but unlike VS C++ the Source Group is not divided into Source Code and Include Files. My question is, do I add a group to Target 1 called Include Files and add to the Include Files Group my dot H files? Because when I did this and built the project I got a lot of WARNING L7: MODULE NAME NOT UNIQUE warnings. In VS C++ there is the dot C++ file and a dot H file with the same name. Does Keil require a different way to include the dot H files?
