Ah yes, I didn't mention it: the program that creates the file completely
fills it with Ctrl-Z characters. So when the data ends, Ctrl-Z characters
will follow. All to the end of the file. A character in the file is either
data,
or it is a Ctrl-Z. It is a bit cumbersome, but I think it is bullet-proof.

Interesting discussion, but it is getting a bit off-topic now, I am afraid.
