       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.


       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           outdated.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.
