title: Changing a batch file when its running
body: <p>I am running a long running batch file. I now realize that I have to add some more commands at the end of the batch file (no changes to exisiting content, just some extra commands). Is it possible to do this, given that most batch files are read incrementally and executed one by one? Or does the system read the entire contents of the file and then runs the job? </p>
