Hi Thomas:

Yes you are right. The Memo info has to be extended to 8 bytes instead of just 4 bytes, this is the part that goes into the dbf. Also the CDX should have a little tweak to make room for record numbers of 8 bytes (64 bits).

Because the VFP dbf header has some unused fields, it could be easily extended to make room for more than 4 billion records, that is the path we are taking for this. The Max record size (64k) is redundant with the 0XD marker for the end of fields, so this could be ignored.
