The group includes:
TRACE0 Takes a format string (Only) and can be used for simple text messages, which are dumped to afxDump.
TRACE1 Takes a format string plus one argument (one variable that is dumped to afxDump).
TRACE2 Takes a format string plus two arguments (two variables that are dumped to afxDump).
TRACE3 Takes a format string plus three arguments (three variables that are dumped to afxDump).
TRACE0 does nothing if you have compiled a release version of your application. As with TRACE, it only dumps data to afxDump if you have compiled a debug version of your application.
