From AutoIt help file > GUIRegisterMsg function > Remarks :- "Warning: blocking of running user functions which executes window messages with commands such as "MsgBox()" can lead to unexpected behavior, the return to the system should be as fast as possible !!!"

Along with "MsgBox()", you can include "_ArrayDisplay()".

#include <Array.au3>
#include <WindowsConstants.au3>
#include <GUIConstantsEx.au3>

Global $a
$hGUI = GUICreate("Window", 500, 400, -1, -1)
$hButton = GUICtrlCreateButton("Button!", 126, 103, 278, 129)
GUICtrlSetFont(-1, 20, 800, 0)
GUISetState()

GUIRegisterMsg($WM_COMMAND, "_WM_COMMAND")
ConsoleWrite("$hButton  " & $hButton & @CRLF)
While 1
    $hMsg = GUIGetMsg()
    Switch $hMsg
        Case -3
            Exit
        Case $hButton
            _ArrayDisplay($a)

    EndSwitch
WEnd

Func _WM_COMMAND($hWnd, $Msg, $wparam, $lparam)
    If BitAND($wparam, 0x0000FFFF) = $hButton Then
        Dim $a = [1, 2, 3, 4, 5, 6]
    EndIf
    Return $GUI_RUNDEFMSG
EndFunc   ;==>_WM_COMMAND
