As I am working through this, in backing up a larger database (+100
meg, not 'large' by any means), I get the following exception:

---------------------------
Debugger Exception Notification
---------------------------
Project trak.exe raised exception class EIBOInterBaseError with
message 'arithmetic exception, numeric overflow, or string truncation
arithmetic exception, numeric overflow, or string truncation'.
---------------------------
Break Continue Help
---------------------------

But this does not hang the application.

The error happens in this code right here:

if Call(dll_service_query(@Unit_Session.Status, @FHandle, nil, 0, nil,
FQuerySPBLength, FQuerySPB,
FBufferSize, FOutputBuffer), False) > 0 then
begin
FHandle := nil;
IBODataBaseError(Self);
end;

which returns a sqlcode of -802.
