Hi Rubens,
There is always more than one way to achieve your goals in programming. Here
is a method that I might've used...

 include Win32lib.ew
 --------------------------------------------------------------
 ------------------
 --  Window Window1
 constant Window1 = createEx( Window, "", 0, Default, Default, 602, 338, 0,
0 )
 
 sequence etid etid = {}
 
 etid &= createEx( EditText, "100", Window1, 8,  32, 70, 20, 0, 0 )
 etid &= createEx( EditText, "100", Window1, 8,  56, 70, 20, 0, 0 )
 etid &= createEx( EditText, "100", Window1, 8,  80, 70, 20, 0, 0 )
                         .
                          .
                          .and so on... a lot.
 
 object etext
 integer cnt
 etext=gets(arquivo) --------some txt archive
 cnt = 1
 while sequence(etext) and cnt <= length(etid) do
   etext=etext[1..length(etext)-1]
   setText(etid[cnt],etext)
   etext = gets(arquivo)
   cnt += 1
 end while
