You're halfway through. The "open" command establishes the connection. The actual data retrieval is a job for the "data" command, which stores the output of an SQL query. Example: <script> qry = "select foo from bar" data myseries query=qry --odbc </script> Riccardo (Jack) Lucchetti Dipartimento di Economia Università Politecnica delle Marche r.lucchetti(a)univpm.it http://www.econ.univpm.it/lucchetti
