String Concat

Hello,

I have a string let's say: "1
2
3".
I want to convert it to:
-- Start SqlServer
BEGIN
{CALL DBA.applsp_ChangeComments( 'ArtPurchPriceUpdate', 'TRIGGER', 'nl', 'ArtPurchPriceUpdate', '1' + CHAR(13)+ CHAR(10) +
'2' + CHAR(13) + CHAR(10) +
3' )}
END;
-- End SqlServer

-- Start Sybase
BEGIN
CALL DBA.applsp_ChangeComments( 'ArtPurchPriceUpdate', 'TRIGGER', 'nl', 'ArtPurchPriceUpdate', '1' + CHAR(13) + CHAR(10) +
'2' + CHAR(13) + CHAR(10) +
'3' );
END;
-- End Sybase

-- Start Oracle
BEGIN
ish.applsp_ChangeComments( 'ArtPurchPriceUpdate', 'TRIGGER', 'nl', 'ArtPurchPriceUpdate', '1' || CHR(13) || CHR(10) ||
'2' || CHR(13) || CHR(10) ||
'3' );
END;
/
-- End Oracle

This works well for oracle and sybase, for sqlserver I can't concatenate in a parameter of a stored procedure. I really want to do this. To create a variable is a lot of extra programming. Is there anyone who knows how to cancat these strings within the stored procedure call?

thanks beforehand,
