When I make a field of the subject type, what is the maximum (largest)
integer I can put into the field. The docs say there is a difference
between signed and unsigned. So where do I "tell" firebird that I
want this to be an unsigned field so I can get the max unsigned
integer value into the field?

If I only enter unsigned values into the field, and never once enter a
signed value, does that mean I can just "keep going" and stuff in
unsigned integer values and just "expect" FB to "know" that I want an
"all unsigned" values field?

Thanks in advance for your help.
