You get at least three other benefits:   You can specify arguments 
(available in sys.argv) for each run, to test the program in various 
ways.  And you can see earlier runs on the screen, and scroll back an 
arbitrary (configurable) amount to see what changed.  And you can 
copy/paste that output elsewhere, like to an email if you have a question.

The value will survive within the one command window, and any other 
command windows you start from it.  But if you want that value to be 
available on all (new) command windows, you set it in the Control Panel. 
  It's been a while since I ran Windows, but it was someplace like 
System->EnvironmentVariables)  Once you do that, it'll not only be 
available in any new DOS sessions, and any application that's run from 
Explorer, but also will survive a restart.
