Let's see if I get this correct... Apologies in advance if not. While browsing the intrinsic/built-in functions documentation, I had to think a bit extra to see what the function did as the example was ambiguous.
Searching for the place to change it, I also realized that the tests were not ideal as the will not detect the (admittedly unlikely) event that a nibble swap instruction is used. BR Oscar Gustafsson
