>288G is x'48_00000000', not x'28_00000000’, I don't know about "28" vs "48" but the values of the boundaries of the area are not considered to be a programming interface and are, as you'd expect, represented in a system control block. I don't know why it was felt necessary (or even appropriate) to put the actual boundaries into a book (the creators of red books seem often do not check to see if what they put in would be deemed OK; yeah, I know we should be able to get our company-wide act together)
