[Pharo-project] OSProcess in Pharo (on Windows)

Forgive me if this question has already been answered, but I can't seem to find it... Is OSProcess running in Pharo, and what is the magic incantation to call an external program, batch file, etc... in Windows? I seem to recall something like: OSProcess thisOSProcess command: 'dosomething.exe' But that doesn't seem to currently be working for me... Thank you, Rob
