Hi,         

   have a look at "calculated fields". Create one of that and set the OnGetText and
OnSetText events with appropriate code. 
Upon displaying, you have to show a modified version of the value of the real data field.
When you modify the calculated field, you have to reflect the changes onto the data field,
obviously after you have made the appropriate calculations. 
This should work fine, especially if you hide the underlying field, setting his Visible
property to false.

Regards

Giuliano
