Mapping variable-length fields to fixed-length fields
If the data length of the from-field is less than or equal to the to-field length, the
data is copied to the fixed-length to-field and padded to ensure data integrity.
If the length of the from-field data is greater than the to-field length, the from-field
data is copied to the to-field and truncated on the right in a manner that ensures
data integrity.

If the to-field has a maximum length greater than or equal to the from-field length,
the from-field data is copied to the data portion of the to-field and padded to the

from-field length.
