DESCRIPTION

       The  PDB  (Pilot  Database)  file  format  is used by all models of the Palm Pilot and IBM
       Workpad.  The format consists of a header followed by a set of record headers followed  by
       the records themselves.

   Word Sizes
       In the SYNOPSIS above, the types ``Byte,'' ``Word,'' and ``DWord'' are used just as in the
       Pilot headers.  The type ``Byte'' is 8 bits; ``Word'' is 16 bits; ``DWord''  is  32  bits.
       The latter two are in big-endian format.

CAVEATS

       1.  The C structures given in the SYNOPSIS above are illustrative and most likely will not
           work in actual C code since compilers align data members on word boundaries.

       2.  The PDB file format presented here is not official and was written at  the  time  when
           PDB  file  format  was  not public. It is possibly outdated.  The official standard is
           available on the Palm web page. (SEE ALSO)
