The Interactive
SQL Classic (dbisqlc) utility executes SQL statements against a database. This utility is deprecated.
The utility is similar to the Interactive SQL utility, except that it is not
            implemented in Java. The absence of Java can be an advantage if you are deploying the
            utility to a computer with limited resources. 
Note: Interactive SQL Classic is deprecated; however, there are currently no plans to
                remove it. Interactive SQL Classic is provided for backwards compatibility for
                running SQL scripts and as a lightweight tool for deployment. It does not support
                all the features that Interactive SQL supports and may not support all the features
                available in the current version of SAP Sybase IQ. Use the
                Interactive SQL utility instead.
The Interactive SQL Classic utility is supported on Microsoft
Windows and UNIX.
