SSIS passing result set from one sql task to other

i have a sql task which executes a stored procedure which has some variables in it,i want to use the result set to input to next sql tasks in ssis.how do i achieve this.
it looks like this

cretae proc sp1(@ par1 int,@par2 varchar(50),@par3 varchar(50))
as begin
declare @var1 varchar(50)
declare @var2 int
declare @var3 int

update -----

insert----

select @var1=some calculated value
select @var2=some calculated value

end

create proc sp2(@var1 varchar(50))

create proc sp3(@var2  int)

i am using a sql task to execute the sp1,i need to givs these varibles inside the sp1 as the parameters to next 2 sql tasks which executes sp2 and sp3.how can we do this.


Thanks
