How does a subroutine end in a GOSUB command?

The subroutine must end with a RETURN statement. The subroutine is invoked with a GOSUB command from another part of the batch file. After the RETURN, processing will continue with the command following the GOSUB command. For example, the following batch file fragment calls a subroutine which displays the directory and returns:

What does the structure of a subroutine look like?

The structure looks like this: The call command followed by a colon and a label name tells CMD to continue processing at the label. Any items placed on the call command after the label are arguments passed to the subroutine, which can access them with %1, %2, and so on.
