Jef - this will select one or all records in the file with the oldest
date (if it's possible that the oldest date is duplicated)

select * --- replace the asterisk with the fields you need --
 from myfile a
 join (select b.division,
              b.account,
              b.po#,
              max(b.cdate) as chgdate
         from myfile b
     group by b.division,
              b.account,
              b.po#
     order by b.division,
              b.account,
              b.po# ) b
  on a.division = b.division
 and a.account = b.account
 and a.po# = b.po#
 and a.cdate = chgdate
