Hello,
I have had a look in the April draft, but I think that there is a small
ambiguity about eof() methods in streams.
Is the eof-flag raised, when the end of the stream is reached, or when
an attempt to move past this end is made? I think the most common
practice is the latter, but the ANSI draft uses the former statement.
Declaring the end of a stream as the first charachter _after_ the last
character of the stream would rescue the expression, but wouldn't fit
into a concept of an end. (Usually one thinks of an end as belonging to
the whole)
As I am rather convinced, that the eof is raised at an attempt to meove
past the end, I'd like to ask how to check this in a binary file without
having to perform a movement.
Regards,
Axel.
