This output instruction operates on the contents of data Files A and B and
places the result of the operation OR in File R (Figure 16.1).
The logic operation OR compares each bit in File A to the corresponding
bit in File B. If either of the bits is a 1, a 1 is stored in the corresponding
bit location in File R. If neither of the compared bits is a 1, a 0 is stored in
File R (Table 16.B).
