DBX_CMP_ASC, DBX_CMP_DESC flags. Default comparison changed from DBX_CMP_TEXT to new DBX_CMP_NATIVE. Solved bug in associative fields when using mssql Cleaned up comments (/*/ ... /*/ to /* ... */) dbx_connect now always return false if the database is not found. Optimized dbx_query field-info retrieval loop
