Clear Static Array

[seadoggie01]

How do we wipe a static array without resizing the elements? I've gotten errors each time I've tried.

Background: I'm attempting an error stack because I'm lazier than water... I don't want to make all my error numbers unique. I also realized that I needed to resize the array to 0 since I'm returning the whole stack, but now I'm curious if this is possible.

Func __ErrorStack($iError = 0, $sFunction = "")
    
    ; The static error stack
    Static $aErrors[0]
    
    ; If the user wants the stack
    If $iError = 0 Then
        ; Copy the errors
        Local $aRet = $aErrors
        ; Clear the error stack
        <Keyword> $aErrors[1]       ;<--- Error line
        ; Return the error stack
        Return $aRet
    
    ; Otherwise, I'm adding an error
    Else
        ; Resize
        ReDim $aErrors[UBound($aErrors) + 1]
        ; And add
        $aErrors[UBound($aErrors) - 1] = $sFunction & ":" & $iError
    EndIf

EndFunc

I wasn't sure, so I tested.

; I really expected Static to work... the variable already is static... why is it trying to make it static again?
Static $aErrors[1]  ; Cannot make existing variables static.
ReDim  $aErrors[1]  ; Works... but doesn't clear the first element
Local  $aErrors[1]  ; Cannot make static variables into regular variables.
Dim    $aErrors[1]  ; Cannot make static variables into regular variables.
; These repeat their respective errors above
Static $aErrors
Local  $aErrors
Dim    $aErrors

Is this possible with static arrays?

I can think of two solutions:

1. ReDim to 0 and ReDim back up to the original, but that seems weird. 
2. Declare and overwrite with a second variable, again, that seems clunky

This ?

#include <Array.au3>

_Stack (2)
_Stack (5)
_Stack (0)
_stack (2)

Func _Stack ($iNum)
  Static $aErrors[1] = ["Test"]
  ReDim $aErrors[$iNum]
  _ArrayDisplay ($aErrors)
EndFunc

Never mind. I realized I'm thinking in VBA again where using Dim a second time will create an array of the same size with empty elements. Sorry about that. I've been using Macros too much lately

No need to be sorry.  Happens...
