Pass Multiple Parameters To Stored Procedure

Hi,

I want to create a stored procedure which I can pass multi parameters. This is what I need, I have a gridview which is used for displaying customer info of each agent. However, the number of customers for each agent is different. I will pass customer names as parameters for my stored procedure. Here is a sample,

CREATE PROCEDURE [dbo].[display_customer]

@agentID varchar(20), 

@customer1 varchar(20),

@customer2 varchar(20),

.....            -- Here I do know how many customers for each agent

AS

SELECT  name, city, state, zip

FROM rep_customer

WHERE agent = @agentID and (name = @customer1 or name = @customer2)

Since I can not decide the number of customers for each agent, my question is, can I dynamically pass number of parameters to my above stored procedure?

Thanks a lot!
