It sounds like a good plan. (I forgot to make use of the Local Record ID).
Thanks.

The way I normally deal with it is that I know it's a new record if
there is no mapping record from the Palm local id to the pc/server
database unique id. (You can't set the id of a record on a Palm, so
there is normally a table mapping Palm records to pc/server records.)
This method works both ways; a new pc/server record won't have an entry
in that table either.
I find it helps to draw up a matrix of possibilities with Palm records
on one axis and PC/server records on the other. Then list all the
possible things that can happen to a record : no change, doesn't exist,
modified, deleted, archived, etc. Then fill in the action required for
each case (append to pc, append to Palm, overwrite PC, etc).
The new record cases are now the (modified,doesn't exist) pairs.
Cheers,
Jim Cooper
