Help with xdotool and XOJO

I am trying to place and size a window on Mac using XOJO as my coding app. I am NOT in Terminal. Needs to be run as a shell I guess, but I don't know how to get the variable or set the variable.

Here is a line of code that opens a folder:

Dim sh As New Shell()
  sh.Execute("open /Users/shawn/Desktop/ATP")

how do I get the xdotool to place a size the active window.

xdotool getwindowpid
xdotool windowmove
xdotool windowsize
