Today we'll have a look at the instance of EmSystemConfiguration that gives you access to a number of basic APISs - System. If you browse the class, you can get a deeper idea than what we'll touch on here. Here's a list of some of the more useful things available:

System settings	

System confirm: 'Should We Proceed?'

System imageVersion.

System vaVersion.

System vaVersionId.

System vmVersion.

System vmVersionId.

System saveImage.

System exit.

You can get the settings (from your default ini file), the version of the product you're running (useful if you need to support multiple versions of VA), pop up a simple confirmation dialog - and save or exit the image
