How to access a field of an data source w/o binding a form field to it

Question

Hi
  This is a query regarding ADOBE print form.
  How to access a record field (of an data source.... typical multi row records) where the record is bound to a subform.
Data is something like
(I have used abap parlance for understanding)
data : begin of data_tab occurs 0,
  field1 type .....,
field2 type .....,
fieldm type .....,
fieldn type .....,
end of data_tab.
Subform is bound to
$.DATA_TAB.DATA[*]
How to access field1, field2,...... etc without creating subform fields and binding them to field1, field2, .... fieldn.
I know normal approach is to define subform fields and then bind it to $.field1, $.field2 etc
In the calculate event of a field bound to $.fieldm I have tried the following expressions to get the value of column fieldn of the same record but none of them worked.... Note that if I bind the field using $.fieldn data is displayed properly in the print form.
$record.data_tab.fieldn.value
$record.data_tab.data[*].fieldn.value
$record.data_tab.data.fieldn.value
$record.data_tab.fieldn.value
Otherwise I would have to define hidden fields just to use these column values in the event script even though these value are not to be displayed in the ADOBE print form.

I can't remember the exact sentence, but do a little search, as that is a common question in this forum....
How about:
$record.data_tab.data[1].fieldn.value
$record.data_tab.data[2].fieldn.value
$record.data_tab.data[2].fieldn.value
$record.data_tab.data[N].fieldn.value
Cheers.
