Long records

In Unicode mode, it is possible to process records of up to 32768 characters in length. At the IEDTGLE interface, it is possible to transfer records of up to 32768 bytes in length (as in the DMS).

This does not require any extension of the IEDTGLE interface. This also applies to the IEDTGLE interface in V16 format. The user must make sure that the buffer is sufficiently long.
