row number with in cursor

Something like this:

for currDateRate  IN  currDR( rate_in,  start_date )  LOOP

  raise notice ' currDateRate.rate_date: %', currDateRate.rate_date ;
  raise notice ' currDateRate.lag_r_value: %', currDateRate.lag_r_value ;
  raise notice ' currDateRate.rate_value: %', currDateRate.rate_value ;
  raise notice ' currDateRate.overnight_r: %', currDateRate.overnight_rate_return ;
  tr_index  :=  tr_index  *( 1+ currDateRate.overnight_rate_return  )  ;
  raise notice ' tr_index: %',tr_index ;

  raise notice ' row number %', currDateRate%ROWNUMBER ;
 
End LOOP;

for testing purposes would like to break out after twenty records.

Yes I know I could do a simple counter like this:

  rtn_cnt :=  rtn_cnt +1;
  if rtn_cnt  >= 20  then
      return  rtn_cnt;
  END IF;   

thamks for your attention to this matter
