Hello fellow stackers

Please consider the following SQL Server table and stored procedure.

create table customers(cusnum int, cusname varchar(50))

insert into customers(cusnum, cusname) values(1, 'Ken')
insert into customers(cusnum, cusname) values (2, 'Violet') --The Wife

create procedure getcus 
  @cusnum int
as 
Begin
   select cusname
   from customers (nolock)
   where cusnum = @cusnum
End

You know how you can write T-SQL code like this:

declare @cusname varchar(50)

select @cusname = cusname
from customers 
where cusnum = 1

Can I do this with my stored procedure?

for example the code would look like this:

declare @cusnum int
declare @cusname varchar(50)

set @cusnum = 1

exec @cusname = cusname pbogetcus @cusnum

Thanks in advance.
