Here's how most people's loops look.

with my query do begin

Open;
while not Eof do begin
...
Next;
end;
end;

What would happen if once the record hit the last row if it also reported
Eof = true?

From what I can tell, you would not process the last row because the loop
would be exited.

I think the behavior of Bof and Eof should be the same.

You need to change your logic to probe for Eof and Bof and avoid it
accordingly.

> Hello All,
>
> I am in the process of converting over to IBO from the BDE. I replaced a
TTable with the TIB_Query. I load the TIB_Query with a SQL string like
"SELECT * FROM TICKET_INFORMATION ORDER BY ACTIVE_DATE DESCENDING". It
fetches the records but the Bof and Eof don't seem to work properly. The
don't seem to realize that I am on the first or last record until I go past
them.
