Func _UDPServiceIsOk($addr,$port)
    UDPStartup()
    $exit = UDPOpen ( $addr, $port)
    MsgBox(0,'', $addr & "  " & $port &   "  " & $exit)
    UDPShutdown()
    if $exit == -1 then Return False
    Return True
    
EndFunc


_UDPServiceIsOk('',53)

as far as i understand, it must return -1. But return value is empty string - ""

It returns an array when there is no error. $exit cannot be displayed as a string because it is an array instead.
