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 ACCU 2. The address of the destination field is in ACCU 1.
The higher address of each field must be specified because a field transfer takes place by
decrementing. The bytes in the destination field are overwritten during the transfer.
