This configuration variable controls whether the Acu4GL for Sybase interface checks for the tablename_update stored procedure when opening a table. If A_SYB_CHECK_UPDATE_SP is set to FALSE (NO, OFF, 0), the Acu4GL interface does not check for the stored procedure. Therefore, even if tablename_update exists, it is not used if A_SYB_CHECK_UPDATE_SP is set to FALSE. The default is TRUE (YES, ON, 1) to check for the stored procedure.
