What is Best Way to Implement Platform Character Control from TouchGUI Joystick?

I'm implementing a mobile touch GUI and want to use the GUI user Input to control the character controller. I have the GUI joystick coded and all it does right now is detect when user leaves the touch stationary over the GUI.

Here is the Joystick script:

 var GUI_LeftArrow : GUITexture;
 var GUI_RightArrow : GUITexture;
 
 function Start() {
     GUI_LeftArrow = GameObject.Find("GUI_LeftArrow").guiTexture;
     GUI_RightArrow = GameObject.Find("GUI_RightArrow").guiTexture;
 }
 
 function Update() {
 
     for (var touch : Touch in Input.touches) {
         if (touch.phase == TouchPhase.Stationary && GUI_LeftArrow.HitTest(touch.position)) {
         
         guiText.text = "Left Arrow Down";
         }
         
         else if (touch.phase == TouchPhase.Stationary && GUI_RightArrow.HitTest(touch.position)) {
         
         guiText.text = "Right Arrow Down";
         }
         
         else {
         guiText.text="NONE";
         }
     
     }
 }

This script is attached to the TextureGUI.

I don't want to implement character control in this script because I want the character controller to be a component of the character object, not the joystick Texture GUI.

What is the best way to do this? Can I set a global bool within this joystick script and then have another script (that is a component of the character object) retrieve the bool. How would I be able to implement that, where does that Global bool get saved to and how do I retrieve it? How do static functions play into this notional scheme?
