MBSL(––) multiplies the 32-bit (8-digit) signed binary data in Md+1 and Md
with the 32-bit signed binary data in Mr+1 and Mr, and outputs the 16-digit
signed binary result to R+3 through R.
Note Refer to 1-7 Calculating with Signed Binary Data for more details.
ER: Indirectly addressed EM/DM word is non-existent.
(Content of *EM/*DM word is not BCD, or the EM/DM area boundary
has been exceeded.)
EQ: ON when the result is zero (content of R+3 through R all zeroes), oth-
erwise OFF.
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 01.
