? local arrays retain size between function calls?

; ?? seems like the array is not destroyed when subroutine is exited
; Script Start - Add your code below here
#include <Array.au3>

Global $sWhereAreWe = _GetDirParent(@ScriptDir) ;; "R:\Operations\MacroTools\_RejectServiceRequestsNotInError\Programs\
Global $sWhereAreWeA = _GetDirParent($sWhereAreWe) ;;"R:\Operations\MacroTools\_RejectServiceRequestsNotInError\
MsgBox (0, "", $sWhereAreWe & @cr & $sWhereAreWeA  & @CR & @ScriptDir )

Func _GetDirParent ($sMyDir) ; no need for input parms, we will find where we run from

Local $text = $sMyDir ; & "\"  ;
Local $array = StringSplit($text, '\', 1)
MsgBox (0,"text",$text)

Local $iUpperBound = $array[0]
Local $iI
Local $sParent = ""

For $iI = 1 To $iUpperBound -1
    $sParent = $sParent & $array[$iI] & "\"

 MsgBox (0," ", $sParent)
Return $sParent

; Local $sS = _GetDirParent()


the above code attempts to find the Parent folder of the folder provided.

It fails because the Array called array retains its upperbound between calls.

I would have thought arrays would be destroyed after the function closes and recreated with new bounds.

Is this an expected effect?

Is there anyway to force the array to be deleted and created with new bounds.

You add a trailing "" after each level of the parent - so when you next split you have an empty element in the array. If you remove that trailing "" then the function works as you wish:

For $iI = 1 To $iUpperBound - 1
    $sParent = $sParent & $array[$iI] & "\"
$sParent = StringTrimRight($sParent, 1)
All clear? :)
