Many people have mentioned data streams. But since you said 'end of file' I wonder if you are referring to the DOS idea that ^Z is an end of file marker, and many apps won't look beyond it. For instance, given a file like: ====start==== 1 2 3 4 5 6 7 8 9 ====end==== the command 'type test.txt' provides: ====start==== 1 2 3 4 5 ====end==== If that is indeed what you are thinking of, it only applies to text files, not to binary files. -- Karl DeBisschop <[EMAIL PROTECTED]> _______________________________________________ Full-Disclosure - We believe in it.
