Call PrefSetAppPreferences with a NULL pointer and/or 0 size. (4th and 5th
parameter).
For example:
PrefSetAppPreferences('ABCD', 0, 0, NULL, 0, true)

For record databases, the database header contains, for each record, a
3-byte unique ID, along with 4 bits of category, and 4 bits of attributes
(deleted/busy/dirty/secret).
For resource databases, the database header contains, for each record, a
4-byte type, and a 2-byte ID. The resources you create in constructor map
directly (except for menus) into corresponding resource in your application
(resource database).
