Assign function code to a field in internal table

Question

Hi all,
Can we assign a function code to one field in internal table so that we can use it as an user command in list display.
For ex:
data : begin of itab occurs 0,
          check(1) type C,
          num type I,
         end of itab.
I am preparing a list display using WRITE statements.
I'ld like to update the checked value of check box as soon as the user selects a  check box. So I would like to assign a function code to this check box. Then I can use AT user-command.

Hi,
dinesh's apporach is not bad, but
1. the structure' name cannot be part of the component
2. you need to make sure the component-name always is in upper case.
Try adapting the following code:
data: begin of wa_test,
          field01 type string,
          field02 type string,
          field03 type string,
       end of wa_test.
data:  l_fieldname  type string,
       l_counter    type string.
field-symbols: <testc> type string.
do 3 times.
  l_counter = sy-index.
  concatenate 'field0' l_counter into l_fieldname.
  translate l_fieldname to upper case.
  assign component l_fieldname of structure wa_test to <testc>.
  if <testc> is assigned.
    <testc> = 'any value'.
  endif.
enddo.
write / wa_test-field01.
best regards
