Error assigning varchar2 value to an output varchar2 parameter

Question

I do not understand why is the procedure erroring out while assigning value to an output parameter.
It gives ORA -06502 ; numeric or value error
character string buffer too small
Procedure is doing something like this
Procedure Test ( logs_tats out varchar2,
log_num out number,
check_num in number) as
v_stats varchar2(400);
begin
if (check_num = 0) then
v_stats := 'Check something and check something else';
end if;
if( check_num +3 <10) then
v_stats := v_stats || chr(13) || 'Check something and check something else';
end if;
if (check_num +5 <15) then
v_stats := v_stats || chr(13) || 'Check something and check something else';
end if;
log_stats := v_stats; -- gives error at this line
check_num :=0;
exception
when others
--raise_application_error()  statement
end Test;
I also tried with removing all 'chr(13)' that I am using and it still gives an error at very that line,
i tried doing a dbms_output to check the length of v_stats just before error and it is 287.
Is there any upper limit on the size of output varchar2 ?
thank you

How about you try posting the actual code and actual attempt to call it (SQL Plus is great for doing this).
Procedure Test ( logs_tats out varchar2,and then later
log_stats := v_stats; -- gives error at this lineYou misspelled the out parameter in the procedure declaration.
Some notes
1) use the code tags so your code stays readable
2) give us complete details including an oracle version
3) use some naming standard for your variables
   pi_ --> parameter in
   po_ -->parameter out
   l_  --> local
... etc
Makes life easier (pick any standard you find useful and easy to understand).
