	If you're using the ColdSync.pm Perl module, then $PDB will
automatically be written at the end of the sync. It will be written to
the file given by the "OutputDB" conduit header.
	Otherwise, you can always use

	$PDB->Write("/path/to/file.pdb");

	Look in the Palm Software Developer's Kit (SDK). Specifically,
in the file Incs/System/DLCommon.h:

    //////////////////////////////////////////////////////////////////////////
    // dlpDeleteRecord
    //////////////////////////////////////////////////////////////////////////
    //
    //    Possible error codes
    //       dlpRespErrSystem,
    //       dlpRespErrParam,
    //       dlpRespErrNotFound
    //       dlpRespErrNotSupported
    //       dlpRespErrReadOnly
    //       dlpRespErrNoneOpen
    //

    // Request argument structure:
    //
    #define dlpDeleteRecordReqArgID  dlpFirstArgID

    // Argument structure to delete by record
    ID(dlpDeleteRecordReqIDArgID):
    typedef struct DlpDeleteRecordReqType {
                                    // OFFSET
       Byte              dbID;          // 0;    database id
       Byte              flags;         // 1;    flags (dlpDeleteRecFlagDeleteAll)
       DWord             recordID;      // 2;    unique record id (see flags)
                                        // TOTAL: 6 bytes;
       } DlpDeleteRecordReqType;

    // dlpDeleteRecFlagDeleteAll: if this flag is set, the reocordID field
    // is ignored and all database records will be deleted
    #define dlpDeleteRecFlagDeleteAll      0x80

    // dlpDeleteRecFlagByCategory: if this flag is set, the least significant byte
    // of the reocordID field contains the category id of records to be deleted
    #define dlpDeleteRecFlagByCategory     0x40

    // Response argument structure:
    //
    //    none.

So set 'flags' to 0x80.
