Variables scope question.

Look at this example code.

How is that possible that myFunc can access $input2 value? I don't pass it as argument.

#include <guiconstants.au3>
ShowGUI()

Func ShowGUI()
   GUICreate("My GUI")
   $Input1 = GUICtrlCreateInput  ( "text1", 10, 10)
   $Input2 = GUICtrlCreateInput  ( "text2", 10, 30)
   $Input3 = GUICtrlCreateInput  ( "text3", 10, 50)
   GUISetState (@SW_SHOW)
   
   $msg = GUIGetMsg()
   myFunc($input1,$input3)
EndFunc 

Func myFunc ($first,$second)
   For $i = $first to $second
      MsgBox (0,"",GUIRead ( $i ))
   Next
EndFunc

Myfunc doesn't access $input2.

This will be the values for $input?;

$input1 = 1

$input2 = 2

$input3 = 3

You tell MyFunc to retrieve the values for control 1 to 3.

MyFunc itself does the retrieval itselve for the 3 controls.

define $input2 as a global variable at the begining of your script
