Limitations
R and R+1 must be in the same data area.
Description
When the execution condition is OFF, MLB(52) is not executed. When the ex-
ecution 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 leftmost four
digits in R+1.

Precautions
MLB(52) cannot be used to multiply signed binary data. Use MBS(––) instead.
Refer to 5-20-7 SIGNED BINARY MULTIPLY – MBS(––) for details.
