DBase III format

Byte	Description
0	03h, version number (83h if there are memo fields)
1-3	Last update, YY, MM, DD
4-7	number of records, 32 bit integer
8-9	length of the header structure, 16 bit integer
10-11	length of a record, 16 bit integer
12-31	reserved
32-N	Field Descriptors This is an array of 32-byte descriptors, one for each field in the record, up to 128 fields.
	Byte	Description
	0-10	Field Name (padded with nul)
	11	Field Type C Character N Numeric (-.0123456789) L Logical (YyNnTtFf) (? if not initialized) D Date (YYYYMMDD) M memo
	12-15	reserved
	16	Field Length
	17-31	reserved
N+1	0Dh field terminator

Data records begin after the header.
One byte precedes each record: blank if valid record otherwise asterisk represents a deleted record. No separators, delimiters or terminators are used in the data records. All fields are packed.

Memo fields:
A memo field is 10 bytes wide, and is the alpanumeric representation of a block number (starting with 1) in the corresponding ".dbt" file. You may assume a memo is less than 500 bytes to avoid the case of "chaining" blocks. The text within a block is terminated with two bytes of 0h1A. Blocks are 512 bytes. The first (zero) block can be ignored.
