The format originated back in the CP/M days when DBASE and other
BASIC programs used this as their internal format.  The format is
used today for interchange of information between programs with
different internal formats such as DBASE III and Supercalc or 123.

Two double quotes in a row within a string.

I have not seen a DATE type field.
