Just to be aligned with the naming in the OPEN Alliance specification
document, used the same name as it is. wnr and prote are taken from the

Still if you feel like using "write" instead of "wnr" and "protect"
instead of "prote", I will change them in the next revision.

Sure, will do it in the next revision.
