* PDA data structures *

** Custom types used in Palm storeage

Length: 	15 bytes
Fields: 	[14|1]
Fieldnames:	[barcode|null]

Stored as null terminated strings.

Clothing Bit Fields (indicated below as Clothing)
Length:		32 bits
Fields:		[4|4|4|4|4|3|3|3|3]
Fieldnames:	[shirt|pants|undies|socks|shoes|hat|gloves|coat|other]

These are all interpreted as unsigned x-bit integers.

** PDA Record formats

All fields on the PDA side are word (2-byte) aligned. The compiler
inserts null bytes in the records to enforce this constraint.
This is indicated by a null* below.

Scan Record
Length:		38 bytes
Fields:		[15|1|4|15|1|4]
Fieldnames:	[personBarcode|null*|timestamp|serviceBarcode|null*|value]
	union	[personBarcode|null*|timestamp|serviceBarcode|null*|clothing]

personBarcode=	Barcode
timestamp=	int, # seconds from 12:00 A.M. on January 1, 1904 to present (Mac format)
serviceBarcode=	Barcode
value=		int (scan record type specific interpretation)

Length:		36 bytes
Fields:		[15|1|21|1]
Fieldnames:	[personBarcode|null*|name|null*]

The very last null* is a hypothesis that has not been tested. It may
be the case that null*'s are only needed between fields in a single
record and not for the last field of a record.
