OUT varchar2 param throwing ORA-06502: variable too small

Question

Here's a cut down version of my procedure:
create or replace procedure x(o_log OUT varchar2)
as
v_log varchar2(2000) := 'Starting this log file...';
BEGIN
---do various commands and append to v_log with the results --
o_log := v_log;
END;
When I execute, it works fine until the string gets too large - however, it is nowhere near 2000 chars yet.
Is there a limit on the size of an OUT parameter? Is there a way to specify length of o_log?
Thanks

v_log varchar2(2000) := 'Starting this log file...';declares v_log to have a maximum size of 2000 bytes. Depending on your character set, that might be less than 2000 chanracters.
The maximum size allowed is 32,767. For longer strings, use a CLOB.
It's up to the calling routine to make sure o_log is big enough to handle the results. Nothing you can do in procedure x can change the size of a variable declared in procedure y.
