How to break line ?

While raising application error ( from a Pl/Sql trigger), I am displaying a big message which is about 200 char long. Is there a way I can split the message into multiple lines? For example: my message is
" You have tried to Insert rows Into %$%$%$^% table where there are
transactions in @#$@##@ table waiting to be approved. Contact Helpdesk with the Item Information "

I want to display it as
" You have tried to Insert rows Into %$%$%$^% table where there are
transactions "in @#$@##@ table waiting to be approved." Contact Helpdesk with the Item Information "

Is there a way I can break messages ? Right now, its a stream of line and I need a way to control it.
Any help is appreciated.
