There are two conditions under which ^Z processing makes sense: 1. While reading from a terminal (incidentally, the only situation where Unix processes ^D) 2. When handling a text file, *AND* the ^Z in question is the very last byte of the file - except that even this case is very rare, and not really worth the bother. In all other situations, a ^Z should not be associated with EOF. (And ^D should only be associated with EOF in case 1.)
