This one is only for those brave souls who've mastered the mysteries of ODBC (OPEN DATABASE Connectivity, Microsoft's contribution to the client-server world). It opens a connection to ODBC and returns the handle to that connection. The handle can then be used in calls to the ODBC API (Application Programming Interface).
nODBCHandle = SYS(3053)We don't know too many people who make direct calls to ODBC. Unless you've paid your dues with the ODBC SDK (boy, Microsoft really is into three- and four-letter acronyms, isn't it?), we suggest you don't do this.
