BCD Calculation Instructions Section 5-20
Example The following example works much like that for single-word subtraction. In this
example, however, BSET(71) is required to clear the content of DM 0000 and
DM 0001 so that a negative result can be subtracted from 0 (inputting an 8-
digit constant is not possible).
