Hi Robert,

I'm not sure, how long your longs and your ints are,
but I've found:

>in SQL Dialect 1, Generators are 32bit integers, in
> Dialect 3 they have 64 bits.

So they are most likely long enough.

More useful information to be found at:

And... Google is your friend, just googling
for firebird generator gave that link first!
