Compatibility Notes A.03

MVA.

When the A and B address controllers indicate UA data, the field lengths are equal (AF = BF) and the value of the final B address is within the A data field [A + 2, A + (2 * AF)], repeat the source data field between the A and B addresses throughout the destination data field.

Cases of overlaping A and B, other than described above, may produce inconsistent results.

B4800 UN-UN or SN-SN:
Source data between A and B addresses will be replicated in B. Rules for padding or truncation remain the same.
UA-UA:
AF does not have to equal BF for replication.
Mixed data types cause unusual results.
B2900
B3900
In all cases, other than the one described, no replication will take place. The result field will contain the same data as if there were no overlap.
B4900
V300
Same as B2900/B3900 except that partial overlapping the literal field will cause the result field to contain the same data as if there were no overlap.
V500 Same as B4900/V300 except that when the A and B controllers indicate UA data, the field lengths are equal (AF = BF) and the final B address is the final A address plus one digit, report an Address Error (AEX = 01) fault.
