Excellent example. I think the problem with the book is they gave everything in hex. And that's not as clear as the binary. If I had converted the hex sample to binary, and did the intermediate calculations, it would have stuck out like Johnny Holmes.

See if this new example helps: select * from YCSC1 where land(YSTAT1, x'40') = x'40' the results of land is simply the results of a binary and between the fields passed. 0110 1101 0100 0000 ------------ 0100 0000 Since were dealing with single byte fields, and x'40' has only one bit on, if my results is equal to x'40' then the YSTAT1 field had bit 7 on.
