When the execution condition is OFF, MLBL(086) is not executed. When the
execution condition is ON, MLBL(086) multiplies the 8-digit content of Md and
Md+1 by the content of Mr and Mr+1, and places the result in R to R+3.
Md + 1 Md
Mr + 1 Mr
R + 1 RR + 3 R + 2

Note With version-2 CVM1 CPUs, mathematics instructions can use symbols. The
instructions corresponding to MLB(082) and MLBL(086) are
*
U(422) and
*
UL(423).
Refer to page 115 for general precautions on operand data areas.
Flags ER (A50003): Content of *DM word is not BCD when set for BCD.
EQ (A50006): The result is 0.
N (A50008): Shows the status of bit 15 of R+3.
Example When CIO 000010 is ON in the following example, the 8-digit content of
D000010 and D00011 is multiplied by 0000 00FF. The 16-digit resultS is stored
in D00020, D00021, D00022, and D00023.
