Moves the single-digit BCD thumbwheel value into an internal integer
register. This is done to properly align the four BCD input signals prior
to executing the BCD to Integer instruction (FRD). The thumbwheel is used
to allow the operator to enter the thickness of the paper that is to be
drilled. The thickness is entered in 1/4 in. increments. This provides a
range of 1/4 in. to 2.25 in.
