(S) and a quantity of consecutive data elements (n). This is moved to the destination device
(D) for the same number of elements (n).
Points to note:
a) If the quantity of source devices (n) exceeds the actual number of available source devices,
then only those devices which fall in the available range will be used.
b) If the number of source devices exceeds the available space at the destination location,
then only the available destination devices will be written to.
c) The BMOV instruction has a built in automatic feature to prevent overwriting errors from
occurring when the source (S - n) and destination (D -n) data ranges coincide. This is
clearly identified in the following diagram:
(Note: The numbered arrows indicate the order in which the BMOV is processed)
d) Using file registers as the destination devices [D]may be performed on all units.
