Ak, that was your private message ?!
Sorry then.
Just Cocoa list is THE ONLY list that I use which on REPLY do not add list
address. Very annoying IMHO. Each time I answer to list, I need second time
resend letter to list also. So I did assume you get the same.

Bill, this is only technical specification.
It means that SqlLite uses
ulong -- as counter of tables.
ulong -- as counter of fields
ulong -- as counter of records.
Remember about 10 years ago, 4th Dimension did have odd limits because they
have used on start ushort or even uchar types for counters?
4D 6 have resolve that problem.
But this technical specification do NOT means in any way that you really can
make such huge dbs. You will wait hours and days for answers. Who need this?

Excellent. Then we have the same interests! :-)
With great pleasure will collaborate with you.
Btw, I wonder. This is your first time you hear about Valentina ?
Valentina is on MAC market from 1998. It have start from Apple Script
version.
A I have told, in near time, we want investigate if we can integrate
Valentina deeply into CoreData. For now Justin uses only bindings.

That was REALbasic projects.
Is that okay ?
Ops...once again, I have only your name in list TO. :-(
