thanks for your help.

One more question,is it possible to use variable for array dimension?

I want to dynamically change it.

Try it

$petCount = 1
Dim $pets[$petCount]
$pets[0] = "ants"

$petCount = $petCount + 1
ReDim $pets[$petCount]
$pets[1] = "bird"
MsgBox(4096,"Pet List", listing($pets))

ReDim $pets[4]
$pets[2] = "cat"
$pets[3] = "dog"
MsgBox(4096,"Pet List", listing($pets))

$petCount = 12
ReDim $pets[$petCount]
$pets[4] = "elephant"
$pets[5] = "fly"
$pets[6] = "giraffe"
$pets[7] = "hippo"
MsgBox(4096,"Pet List", listing($pets))

Exit

Func listing($array)
    Local $i, $temp = ""
    For $i = 0 to UBound($array)-1
        $temp = $temp & " " & $array[$i]
    Next
    Return $temp
EndFunc
