I have some code that uses for loops and I chaged the outer loop into a simple loop and inner loop into a while loop, but the out put is coming out different. The outer loop is supposed to run 3 times while the inner loops is supposed to run 6 times. Wouls someone look at my code and tell me what I have done wrong. Thanks in advance.

Original code
set serveroutput on
declare
v_test NUMBER := 0;
begin
<<outer_loop>>

for i IN 1..3 loop
dbms_output.put_line('Outer Loop');
dbms_output.put_line('i = ' || i);
dbms_output.put_line('v_test = ' || v_test);

v_test := v_test + 1;
<<inner_loop>>

for j IN 1..2 loop
dbms_output.put_line('Inner Loop');
dbms_output.put_line('j = ' || j);
dbms_output.put_line('i = ' || i);
dbms_output.put_line('v_test = ' || v_test);

end loop Inner_Loop;
end loop outer_loop;
end;
/

Modified code

set serveroutput on
declare

i PLS_INTEGER := 0;
j PLS_INTEGER := 1;
v_test NUMBER := 0;

begin
loop
i := i + 1;

dbms_output.put_line('Outer Loop');
dbms_output.put_line('i = ' || i);
dbms_output.put_line('v_test = ' || v_test);

v_test := v_test + 1;
exit when i = 3;
while j <= 2 loop

dbms_output.put_line('Inner Loop');
dbms_output.put_line('j = ' || j);
dbms_output.put_line('i = ' || i);
dbms_output.put_line('v_test = ' || v_test);

j := j + 1;
end loop;
end loop;
end;
