Multiply Double is a 32 bit instruction that
multiplies the 8-digit BCD value in the
accumulator by the 8-digit BCD value in
the two consecutive V-memory locations
specified in the instruction. The lower 8
digits of the results reside in the
accumulator. Upper digits of the result
reside in the accumulator stack.

Description
SP63
On when the result of the instruction causes the value in the accumulator to be zero.
SP70
On anytime the value in the accumulator is negative.
SP75
On when a BCD instruction is executed and a NON–BCD number was encountered.
NOTE:
Status flags are valid only until another instruction uses the same flag.
In the following example, when X1 is on, the constant Kbc614e hex will be loaded
into the accumulator. When converted to BCD the number is ”12345678”. That
numberis stored in V1400 and V1401. After loading the constant K2 into the
accumulator, we multiply it times 12345678, which is 24691356.

X1
Load the hex equivalent
of 12345678 decimal into
the accumulator.
BCD
Convert the value to
BCD format. It will
occupy eight BCD digits
(32 bits).
OUTD
V1400
Output the number to
V1400 and V1401 using
the OUTD instruction.
