>I'm trying to create a Palm DB on the desktop. I've read the docs etc and

>a) I left the creationDate, modificationDate and lastBackupDate as 0

>b) I don't have an appInfo block, so I wrote out a 0 for the appInfoID. I
>understand that this is the offset from the beginning of the file to where
>the appInfo block is. But if you don't have an appInfo block ( and the

>block is not present.
>
>c) ditto for the sort info block - don't have one and used 0 for the offset
>
>d) The RecordListType (pg 20 of the PDB Database Format doc) has a field
>'nextRecordListID'. Again, this is an offset to the next REcordListType.
>I
