>>--EXEC ADO---USING-dataset_name----END-EXEC----><
| dataset_name | The name of the DataSet that becomes the current DataSet for subsequent EXEC ADO processing, or – (dash), which indicates that no default DataSet should be used in subsequent statements. | 
     EXEC ADO
        USING ds
     END-EXEC

Comment:
References to DataTables in EXEC ADO statements that have no USING clause use the current DataSet name.
USING – implies that the statement uses a standalone DataTable rather than a DataTable contained within a dataset.
