    FUNCTION = This DSECT describes the DBCTL unsolicited statistics
               This copybook maps DBCTL unsolicited statistics. The
               storage area is built at the end of each DBCTL session.
               The copybook is used by DFHSTUP and user programs
               requiring access to DBCTL statistics data.
               For Local DL/I statistics see DFHA18DS.
    LIFETIME = Duration of the domain call to statistics domain
    LOCATION = Caller is passed a pointer to the head of the block.
