There's no such thing as "appending EOF". Your problem description is 
far too vague and missing useful information, as well as depending on 
non-Fortran things. Can you come up with a short but complete Fortran 
example that demonstrates whatever problem you're describing?

END= triggers when there is an attempt to read past the end of the file.
