Remarks In the Debug environment, the TRACE macro output goes to afxDump. In the Release environment, it does nothing. This is a convenient way of generating debugging output that will appear only in the Debug version of your program. Example int i = 1; char sz[] = "one"; TRACE( "Integer = %d, String = %s\n", i, sz ); // Output: 'Integer = 1, String = one' -♦-
