See how much easier it is, when you can see the whole picture?Do the macro expansion manually, and you'll see the problem.
I have no idea what you mean by "Do the macro expansion manually".
Perhaps if you posted the whole of the details it might get easier, but one-liners are not much help to a novice.
Are you suggesting I have to modify RemoteXY.h ??
