How do you get a list of all the trigger DDLs?

Question

I want to get a list of all the DB trigger DDLs of owner 'ABS'. I want to do it using 1 SQL statement.
This is what I ran:
SELECT
TO_CHAR(DBMS_METADATA.GET_DDL('TRIGGER', TRIGGER_NAME, 'ABS'))
FROM
ALL_TRIGGERS
WHERE
OWNER = 'ABS';
I get this error: [1]:
(Error): ORA-22835: Buffer too small for CLOB to CHAR or BLOB to RAW conversion (actual: 4414, maximum: 4000)
Then I looked up in the web and they ask to use DBMS_LOB.SUBSTR instead. So I do that:
SELECT
DBMS_LOB.SUBSTR(DBMS_METADATA.GET_DDL('TRIGGER', TRIGGER_NAME, 'ABS'), 32767, 1)
FROM
ALL_TRIGGERS
WHERE
OWNER = 'ABS';
Now I get this error:
[1]: (Error): ORA-06502: PL/SQL: numeric or value error: character string buffer too small ORA-06512: at line 1
Looks like you cannot show more than *4000* chars. There are 43 triggers whose DDL is more than 4000 chars long.
Why is this?
How can I solve my problem?

Herald, fantastic news. SET LONG did the trick.
But I had to put a very big value. 32000 was not enough. Otherwise some of the triggers (big ones) got cut off.
This is my complete code which did it.
SPOOL F:\Channa\zz_zzTemp\Binuka\OutPut.txt
set trimspool on
set pages 0
set long *1000000000*
set linesize 32767
SET TERMOUT OFF
SELECT DBMS_METADATA.GET_DDL('TRIGGER', TRIGGER_NAME, 'ABS')
FROM ALL_TRIGGERS
WHERE OWNER = 'ABS' AND trigger_name NOT LIKE 'BIN$%'
SPOOL OUT
THANKS A LOT. REALLY APPRECIATE IT.
P.S: I had to include the NOT LIKE 'BIN$%' in the where clause because otherwise I got this error:
ERROR:
ORA-31603: object *"BIN$cqXDSqghrFngQKjAJAovgw==$0"* of type TRIGGER not found in
schema "ABS"
ORA-06512: at "SYS.DBMS_SYS_ERROR", line 105
ORA-06512: at "SYS.DBMS_METADATA", line 2805
ORA-06512: at "SYS.DBMS_METADATA", line 4333
ORA-06512: at line 1
no rows selected
I THINK BIN$... triggers are dropped triggers in the DB recycle bin???
