Example
In the following example, MBSL(––) is used to multiply the signed binary con-
tents of IR 101 and IR 100 with the signed binary contents of DM 0021 and
DM 0020 and output the result to LR 24 through LR 21.

Limitations
R and R+1 must be in the same data area.
Description
DBS(––) divides the signed binary content of Dd by the signed binary content of
Dr, and outputs the 8-digit signed binary result to R+1 and R. The quotient is
placed in R, and the remainder is placed in R+1. Refer to page 27 for details on
signed binary data.

ER:
Dr contains 0.
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 content of R (the quotient) is 0000, otherwise OFF.
N:
ON when bit 15 of R is set to 1.
