       DBMS_OUTPUT.PUT_LINE( issuedate_2);
       DBMS_OUTPUT.PUT_LINE( issuedate_3);
     end loop;
   END;

Answer 1

you can’t form the variable name dynamically, create array of dates and increment and assign values.
TRY THIS LINK

issuedate_||cnt := issuedate+cnt;–problem is in BOLD part

Sample :

SQL>   declare
  2  
  3        type date_aa is table of date index by pls_integer;
  4        l_date_aa date_aa;
  5        temp date:= to_date('27-mar-2012');
  6        buckets number:=5;
  7     begin
  8      for elem in 1 .. buckets loop
  9    select temp+1 into temp from dual;
 10    l_date_aa(elem) := temp;
 11    dbms_output.put_line(l_date_aa(elem));
 12    end loop;
 13    end;
 14  /

output:

28-MAR-12
29-MAR-12
30-MAR-12
31-MAR-12
01-APR-12
