As far as I know the internal database unique id is inaccessible from outside (or even
inside) Filemaker, so don't bother trying to use it
You can do serial numbers in variables, but I wouldn't recommend it. I'd use a Global
field in FM to store the current serial number (generated from whatever scheme you
like) and punch this into the serial number field when the record is inserted. You can
then increment the Global field ready for the next insert
A good reason not to use the internal unique id, as a key or for anything else, is
that this value may change, I believe, under certain circumstances. These may include
saving a compressed copy of the database
I'd use your own generated unique ID as the key, always, with FM
