A user specified derived type input/output procedure maybe called
explicitly by the programmer or implicitly by a DT format
specifier.  It may be called from different data transfer
statements which may be applying different formats,
different units, different records, etc.

Some of these items may be changed by the child but for
others it makes no sense to allow changes.

This paper sets ID, POS, and REC as unchangeable
by a child data transfer procedure.
