STEP 5 Operations

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.

Transfer a 12-byte

data field from

address F0A2

address EE90

Load the end address of the source field into ACCU 1.

Load the end adress of the destination field into ACCU 1. The

source address is shifted to ACCU 2.

Transfer the data field to the destination field.
