An example of using this instruction manually to store a number (e.g. 19.333) in the B
register would be to enter 19.333 on the keyboard and then depress the B and
keys. When
the
key is depressed, the data will be transferred to B and the computer will print both the
number and the instruction executed (e.g. 19.333 B
). If B/
were then manually
performed, the same value would be transferred from M to b and the instructions would print
on the tape to indicate that the number previously entered was also transferred to b (e.g.
b
).
