Declaring variable in a function for use in sub-functions

[Mechaflash]

Lets say we've got nested functions.

_Alpha()

Func _Alpha()
  $a = 1
  _Bravo()
EndFunc

  Func _Bravo()
     msgbox(0,"",$a)
    _Charlie()
  EndFunc

    Func _Charlie()
      msgbox(0,"",$a)
    EndFunc

As far as I know, the only way to get the above msgbox() in both _Bravo() and _Charlie() to work properly, either $a = 1 must be declared as Global scope, or $a must be passed to _Bravo() and then passed again to _Charlie(). Is there another way?

You can use global variables or submit a parameter to the function:

_Alpha()

Func _Alpha()
  Local $a = 1
  _Bravo($a)
EndFunc

  Func _Bravo($a)
     msgbox(0,"",$a)
    _Charlie($a)
  EndFunc

    Func _Charlie($a)
      msgbox(0,"",$a)
    EndFunc

Is there another way?

Maybe Herez one

EnvSet('a','nothing')
_Alpha()
Func _Alpha()
  _Bravo()
EndFunc
  Func _Bravo()
     msgbox(0,"",EnvGet('a'))
    _Charlie()
  EndFunc
    Func _Charlie()
      msgbox(0,"",EnvGet('a'))
    EndFunc
