Flags
ER:
Mi, M+1,Su, or Su+1 are not BCD.
Indirectly addressed DM word is non-existent. (Content of
∗
DM word is
not BCD, or the DM area boundary has been exceeded.)
CY:
ON when the result is negative, i.e., when Mi is less than Su.
EQ:
ON when the result is 0.
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).
