A data block is duplicated within the user memory and it is assigned a
different block number. The start address of the new data block is
entered in the address list in DB 0. The start address of the old block is
retained, i.e. the original data block remains valid.
The start address is entered in DB 0 only after the transfer is
completed and all the IDs are correctly entered in the block header.
The duplicated block is therefore only declared valid or existent by the
system program after it has been completely transferred.
