For example, if the value of N is 7, then N divided by 1 is 7 divided by 1. In the case of batch file functions with parameters, a tilde (~) sign is used to access them in the main program along with the positional number of parameter. Similarly, in the case of batch file functions with return values, return values are set in the function using the set command and the tilde (~)... 1. goto label. 3.
