Yes... <blush> I keep forgetting that part...:)
Two more questions from me :
1. Does this mean that you think it's safe to use one generator for
everything?
2. Do we have to use BIGINT in FB1.5 Dialect 3 or could we use
Numeric(18,0) instead? You seem to be implying that there are some
consequences/differences between the two construct.

Thanks in advance,

PS:
I've read somewhere that Delphi 5/6 (with both IBX and IBO) is having
problems with 64-bit integers, due to incompatibilities with the Variant
type, so we cannot use constructs such as :
...
query1['fieldname'] := some_bigint_value;
... or ...
query1.fieldbyname('fieldname').value := some_bigint_value;
...
Or vice versa (getting the value out of the database). But that's a
Delphi specific issue, I think, Off topic here.
