Need to combine 2 sql selects into one stored procedure

I have 2 sql selects that I would like to combine into one.  Basically one is a select for master record and the other is for a detail record.  My ultimate goal would be to list the master record and then list the detail records below it but I have no idea on how to accomplish this.  The current selects are in 2 stored procedures.

Here is the first procedure:

ALTER PROCEDURE [dbo].[Rpt_GAICustomerOrderInformationSp]
(
       @startdate    datetime = NULL
     ,@enddate     datetime = NULL
)
AS

select
      co.co_num,
      co.cust_num,
      co_line,
      coitem.ref_num,
      coitem.ref_line_suf,
      name,
      due_date,
      item.item,
      drawing_nbr,
      qty_ordered,
      uf_shippingtolerance,
      qty_shipped,
      coitem.stat
from
      co, custaddr, coitem, item
where
      co.cust_num = custaddr.cust_num and
      co.cust_seq = custaddr.cust_seq and
      co.co_num = coitem.co_num and
      coitem.item = item.item and
    due_date >= @startdate and due_date <= @enddate and       
      coitem.stat not in('F','C') and coitem.ref_type = 'J'

Here is the 2nd:

ALTER PROCEDURE [dbo].[Rpt_GAIJobInformationSp]

AS

select
      job.job,
      job.suffix,
      job.ord_num,
      job.ord_line,
      jobroute.oper_num,
      (select description from wc where wc = jobroute.wc) as wc,
      job.item,
      jobroute.qty_received,
      jobroute.qty_complete,
      jobroute.qty_scrapped,
      jobroute.qty_moved,
      start_date,
      end_date

From
      job,
      jrt_sch,
      jobroute
Where
      job.job = jrt_sch.job and
      job.suffix = jrt_sch.suffix and
      job.job = jobroute.job and
      job.suffix = jobroute.suffix and
      jrt_sch.oper_num = jobroute.oper_num
      
      
order by job.job asc, job.suffix desc, jobroute.oper_num asc

The records would be connected by co.co_num = job.ord_num and co.co_line = job.ord_line
