sry, for more completed information, it should be, the output should just change the value of "new data", which is fourth column, the "difference", which is the fifth column, and the status, which is the sixth column, if the code, which is the second column, in the input file, is mentioned in waiver file, in first column. But anyway, thanks you guys enthusiatic helping, i have found the solution.
