I will try changing the names of the output variables and the DB provider.
The problem with ODBC is with my app (VB6).
we are using IBOLE to connect to the database for years without problem and I will not change that now.
Perhaps I can use ODBC only to open reports, but I need to think about the pros and cons of that procedure.

Thanks for Your help.

Regards
Diego
