Description
When the execution condition is OFF, MLB(52) is not executed. When the exe-
cution condition is ON, MLB(52) multiplies the content of Md by the contents
of Mr, places the rightmost four digits of the result in R, and places the left-
most four digits in R+1.

5-22-4 BINARY DIVIDE – DVB(53)
Limitations
DM 6143 to DM 6655 cannot be used for R.
DVB(53) cannot be used to divide signed binary data, but DBS(––) can be
used. Refer to
5-22-9 SIGNED BINARY DIVIDE – DBS(––)
for details.
Description
When the execution condition is OFF, DVB(53) is not executed. When the exe-
cution condition is ON, DVB(53) divides the content of Dd by the content of Dr
and the result is placed in R and R+1: the quotient in R, the remainder in R+1.
