        Also, as you say, ESQL makes you only somewhat database independant.
        You still have to use sybase specifics such as CS datatypes.
        ESQL also does not execute a stored procedure by making an
        RPC call. It invokes it by a language call.
        Since ESQL code is converted to DBLIB/CTLIB code by the
        preprocessor, debugging it can be painful.
        ESQL also does not allow you to do certain things such as set
        configuration options.
