When u say trying to connect from other application package, I assume you are not using Centura application to connect SQLBASE DB.
Your first step would be to create a ODBC DSN for SQLBASE and make sure it connects.
Secondly, you need to go thru the database connectivity
manual of that "Other application".
If you are trying to connect from centura , you need to configure SQL.INI file.
