Maybe like this:
$nSize = DllCall("msvcrt.dll","int:cdecl#0","strlen","str","Hello") ; notice the '#0' ConsoleWrite($nSize & @CRLF)
I know it saves only a line of code, or even 3 chars if you use the array as it is
but it looks easier to understand
And besides that, these two: '[]' are very badly located on a german keyboard
