Computed - a field, that is part of a SQL Select statement, but not a
real field in a table
Calculated - a field, that is NOT part of a SQL Select statement, but
calculated by source code in the OnCalculateFields event.

The problem is that even if I mark a calculated field as computed,
that the calculated field is allways readonly (see source Code of
TIB_Statement).
