ORA-01403: no data found when displaying a value from an array

Question

I have a very simple pl/sql procedure like below which gives an error
SQL> exec p_ks2;
BEGIN p_ks2; END;
ERROR at line 1:
ORA-01403: no data found
ORA-06512: at "KINASE.P_KS2", line 21
ORA-06512: at line 1
if i uncomment the for loop the procedure works ... the loop has nothing to do with my array or what i am doing after it..
could anyone help me to understand why i need a loop like that or what i am doing wrong when i am not having the loop there.
---- procedure
CREATE OR REPLACE
PROCEDURE p_ks2 as
TYPE mdata IS TABLE OF number INDEX BY BINARY_INTEGER;
data1 mdata;
k integer;
m number;
begin
data1(1) := 10;
data1(2) := 20;
data1(3) := 30;
data1(4) := 40;
data1(5) := 50;
k :=3;
--for mm in 10..11
--loop
-- m := mm;
--end loop;
dbms_output.put_line('value of data(' || k || '): ' || data1(k));
end;

Answer 1

here is what i am trying.. when i do not have the for loop it fails. when I have the for loop it works eventhough for loop is really not doing anything related to my array.
and in 10.x both works without error.
I noticed you have the for loop uncommented when you posted the screen. Did it work when you have commented those lines out?
