>I was testing out FIXFPT to see how it would handle certain corrupt memo files I have. I found that FIXFPT would detect a bad memo pointer on memo files which had no apparent problem. It consistently found the pointer, calculated from the header file, to be 1 less than what FIXFPT calculated it should be.

Is it fptfix file#18 from download section?

>Looking at the code it determines that the next free block pointer should be:

NextFreeBlockPt = INT((MemoFileSize/BlockSize)+1)

>Is this correct?

No it's not correct and it's actually the same as

NextFreeBlockPt = INT(MemoFileSize/BlockSize)+1

>Or should the correct pointer be just:>

INT(MemoFileSize/BlockSize) 
>or
CEILING(MemoFileSize/BlockSize)

Eaither one should return correct result because there's always whole number of memo blocks in a file. I would go with the second expression, just to be safe.
