That's OK for DOS, bot not for Exec. Exec wants IOStdReq's in terms of byte offsets, and there's only 32 bits in the offset. So your proposal wouldn't work without some modification, to do something like tell Exec that the offset is not in bytes, or put the high-order 32 bits in another place. If you just decreed that the offset was in terms of 'blocks' (which is driver/unit/partition dependent), you'd break all existing I/O requests. ..Bob -- Bob Page, U of Lowell CS Dept. page@swan.ulowell.edu ulowell!page "I can't tell the difference between ABC News and Hill Street Blues" -Bono
