debugging tool to read out variable values?

[skypickle]

I am trying to move the controls indicator by modifying 

Mods\aircraft\FA-18C\Cockpit\Scripts\ControlsIndicator\ControlsIndicator_page.lua

it's pretty much trial and error because i dont know what to modify-I've narrowed it down to this bit

--default    
base.init_pos        = {0,-(1 - 2.0*size_x)}
base.controllers    = {{"show"},{"screenspace_position",2,-(aspect - 2.0*size_x),0},
                                {"screenspace_position",1,0,0}}

but when I change the base initpos to

base.init_pos        = {0,-(1 - 1*size_x)}

I do not get a change in its Y position. I need to raise the controls indicator about 800 pixels.

The default placement puts the indicator in the left DDI (screen 3 in pic below which is 768 x 1024) and I want to move it to the bottom left of screen 2.( which is 3840 x 1600)

 

Being able to read out the real time value of variables in game would help. Is there such a tool?
