How to get a value such as %SystemRoot% into QB64

[hanness]

Let's say that I want to set a variable within QB64 to a value such as Windows %SystemRoot%. Is my only option for doing that to run a shell command, redirect the output to a file, then parse the file for that information, or is there a more elegant way of doing this?
