Flow of Processing
Processing was interrupted for BSET when #1234 was not yet written to DM
0010. Therefore, in the comparison at point *1, the contents of DM 0000 and DM
0001 are not equal and processing stops with A in the OFF state. As a result,
although the contents of DM 0000 and DM 0010 agree at the value 1234, an in-
correct comparison result is reflected in comparison result output A.
