Description
Flags
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.

DBS(––)
Dd
Dr
R
R and R+1 must be in the same data area.
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 29 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.
