Select range of values in dynpro aplication

Question

Hi ,
I have to do some changes on existing dynpro transaction. I have add pop up with two input fields (FROM and TO)
After pressing ok button data should be selected d from internal table for all values  between  FROM and TO ( from the screen) .
As this is a dynpro application iI cannot use select-options statement.
In the internal table where from data should be selected it can be several entries for the value entered on screen, I need all of them . So  if user enterson   FROM = 'B'  TO = ' D'   (from the table i_tab )
I_tab
1 A
2 B
3 B
4 C
5 D
6 D
7 E
I need folowing entries to be selected .
2 B
3 B
4 C
5 D
6 D
Please advice how can I do that without select-option.
Thanks.

Hi ,
I did try and it works in two cases when FROM and TO fields are filled in, and when  o,ly FROM is filed in.
When  FROM is empty and TO field is filled in the range is populated but  no data is selected in folowing loop.
Please advice
r_bname_wa-low = gv_user_from .
r_bname_wa-high = gv_user_to.
r_bname_wa-sign = 'I'.
if  gv_user_from is initial or
    gv_user_to is initial.
    r_bname_wa-option = 'EQ'.  "equal
else.
    r_bname_wa-option = 'BT'.  "between
endif.
append r_bname_wa to r_bname.
loop at i_lrf_wkqu  where bname in r_bname.
     append i_lrf_wkqu  to i_lrf_wkqu_tmp.
    endloop.
