Md and Mr are multiplied and the rightmost four digits of the result are placed
in R; the leftmost four digits, in R + 1.

ER: Md or Mr is not in BCD.
Indirectly addressed DM word is non-existent. (Content of *DM word
is not BCD, or the DM area boundary has been exceeded.)
EQ: ON when the result is 0.
When IR 0000 is ON with the following program, the contents of IR 13 and
DM 05 are multiplied and the result is placed in HR 7 and HR 8. Example
