SP output parameter nText

Respected Memebers,
Is it possible to specify nText as the output parameter of an SP.Since the varchar has the limitation of 8000, could anyone suggest an alternative to get rid of the limitation of varchar and send larrge xml strings as output parameter

I am using SQL Server 2000

TEXT value can be used as a OUT parameter

Could you please show a simple example of how to use it and append text values to it if your time permits
Thanks
George
