Processing a field transfer
A field transfer is processed independently of the RLO.
The parameter indicates the length of the data field (in bytes) that is to be transferred. The field
can be up to 255 bytes long.
The address of the source field is in ACCUM 2. The address of the destination field is in ACCUM 1.
The highest address of each field must be specified. The bytes in the destination field are
overwritten during the transfer.
