It may well be

This is exactly what Im doing, what Im actually doing is seeking to 1024
bytes from the end, then looking for the string
'startref\r\n<number>\r\n%%EOF' where <number> is an integer in decimal
format

I wanted to scan the lines backwards until I found %%EOF (as its likley to
be the last line) and do it that way.  I might do that or might use a regex
and just let that find it.

Cheers
