Carsten,
I don't think I use ODBC (embarrassing but I am not sure). But I will try your suggestion to see if aerror() will populate error array.
Thank you very much.

>>Thank you for the suggestion. I did think about the same approach, which I will implement. It would be better if there was an error number to each error. That way, "translating" error number to a "friendly" message would be easier. I will have to parse the message and find a string by which to decide what friendly message to display.
