Insert new line character into RAISE_APPLICATION_ERROR text

Hi,
I have an exception which should output certain information:

WHEN OTHERS THEN
RAISE_APPLICATION_ERROR
( -20100, 'Unknown Error when attempting to log sql script: ' || i_Scriptname ||SQLERRM ( SQLCODE ) );




Problem is, it seems to output the first error code immedialty after the error text, like so:

BEGIN
*
ERROR at line 1:
ORA-20100: Unknown Error when attempting to log sql script:
Ora_Rat_DatabaseInfo.sqlORA-00920: invalid relational operator
ORA-06512: at "BLAKEYM.PR_LOGSCRIPTSTART", line 55
ORA-06512: at line 2


I'd ideally like to have to the SQLERRM printed on a seperate line so that it would look something like:
ORA-20100: Unknown Error when attempting to log sql script:
Ora_Rat_DatabaseInfo.sql
ORA-00920: invalid relational operator
ORA-06512: at "BLAKEYM.PR_LOGSCRIPTSTART", line 55


\n doesnt seem to work. Does anyone know a way to do this?

use CHR(10) fro new line

eg,

select 'zzzz' || chr(10) || 'aaaaaaaa' || chr(10) || 'bbbbb' from dual;
