Passing command-line argument into a DOS (including Windows) batch file

You can use these variables in a batch file: %0 – the batch file’s name %1 – the 1st argument %2 – the 2nd argument %3 – the 3rd argument … %9 – the 9th argument 
 e.g. Support the content of test.bat is as follows: 
 @echo offecho param0: %0echo param1: %1echo param2: %2echo param3: %3echo param4: %4 
 Then “test a b” gives: 
 param0: testparam1: aparam2: bparam3:param4:
