Web app system command

Hi,
I was wondering whether it is possible to use the system command to execute an external program (running on Windows) and wait for a response in a deployed web app on a Matlab web server?
Also, an other question just came to my mind: what's the best practice to store permanent data and access them in a standalone executable of a Matlab program. Should I create a folder in C\\:Programs or something?

To the question:

Based on the context of your question, maybe worth pointing out that web-deployed and stand-alone-deployed apps will have to deal with paths differently as far as my experience goes.
Not sure about best practices (I would like to know too!), but web apps are run by a guest user on the server (something like MWWebAppClient20XXy), so you just need to make sure whatever path you point to is read-able and/or writeable if you need; so I put a data folder inside its My Documents folder owned by the guest client.

This might be a dumb question but how do you access env variables from matlab? I.e. how would I write a code to compute the user's path?
