thanks enrico I got some idea but I am having one doubt:
How the size mismatch can occur for Individual and First_Name.

The UNION attribute is just a more flexible form of DEFINED,
it just determines the starting point of a field with no checking of lengths IIRC

- DEFINED works only at the 1 level ( or no level ) variables

so to achieve the same result with the defined
You would have to repeat the whole structure
