    ConsoleWrite("tags member not found." & @CRLF)
    Exit
EndIf

;  Get the value at each array index. 
;  Output will be:
;  [0] = home
;  [0] as integer = 0
;  [1] = 22
;  [1] as integer = 22
;  [2] = green
;  [2] as integer = 0

Local $iArraySize = $oTagsArray.Size
Local $i
For $i = 0 To $iArraySize - 1

Local $sValue = $oTagsArray.StringAt($i)

    ConsoleWrite("[" & $i & "] = " & $sValue & @CRLF)

Local $iValue = $oTagsArray.IntAt($i)
    ConsoleWrite("[" & $i & "] as integer = " & $iValue & @CRLF)

;  Note: The StringAt method returns the value as a string regardless of the type.

;  The IntAt method returns the value as an integer.  If the value does not convert to 
;  an integer, then 0 is returned.
