Hi Richard,

The 10 byte value within the MEMO field of the .DBF file
  stores the memo file block number as a stringified number.
  So, the maximum unique values here would be 9,999,999,999
  ("9999999999').  However, since this value is then
  multiplied by the .FPT block size (stored in the .FPT
  header and set to 64 by default), and since the pointer to
  the block is held in an unsigned long integer (max 4Gb
  value), the maximum value that would work in the MEMO
  field pointer value should be 4Gb divided by the block
  size (64), or about 64 million.
...I think.  <g>

Best regards,
Loren Scott
