Passing Options to File.execute

I'm trying to make a GUI for my command line tool using ExtendScript CS6 (Photoshop Script) at the moment I'm able to execute the file via...

    var myFile = File("/c/path/to/my/tool.exe");

    myFile.execute();

However what I really need to to be able specify the working directory and to pass command line options to the executable such as "--help" or "--input path/to/input/dir/" and etc.

Is there anyway to do this (even by proxy)?

(also where can I find the docs for objects like File is there a ASDocs/JavaDocs html page similar to this)

Thanks in advance,
