Description
Flags
168
When IR 00000 is ON with the following program, the content of IR 020 is
divided by the content of HR 09 and the result is placed in DM 0017 and DM
0018. Example data and calculations are shown below the program.

When the execution condition is OFF, DIVL(57) is not executed. When the
execution condition is ON, DIVL(57) the eight-digit content of Dd and D+1 is
divided by the content of Dr and Dr+1 and the result is placed in R to R+3:
the quotient in R and R+1, the remainder in R+2 and R+3.
Remainder
R+3
Dr+1
ER: Dr and Dr+1 contain 0.
Dd, Dd+1, Dr, or Dr+1 is not BCD.
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 result is 0.
