Also, back in the 370/165/168 era, there was a definite performance difference for MVC (and maybe MVCL) when the source and destination addresses did not reference bytes at the same offset within their containing double words. I don't know if this is still a consideration - don't have access to anything but my Mac or my wife's Windoze these days.
