arguments
  arg1 : Path to the executable file to debug. If no full path is given, the GetCurrentDirectory API will be called to retrieve a full path. Use quotation marks to include spaces in your path.

[arg2]: Commandline to create the process with.

[arg3]: Current folder (passed to the CreateProcess API).

result
This command will give control back to the user after the system breakpoint is reached. It will set $pid and $hp/$hProcessvariables.
