Precautions DVB(53) cannot be used to divide signed binary data. Use DBS(––) instead. Re-
fer to 5-20-9 SIGNED BINARY DIVIDE – DBS(––) for details.
Flags 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 result is 0.
N: ON when bit 15 of R is set to 1.

Limitations Au and Au+1 must be in the same data area, as must Ad and Ad+1, and R and
R+1.
Description When the execution condition is OFF, ADBL(––) is not executed. When the
execution condition is ON, ADBL(––)) adds the eight-digit contents of Au+1 and
Au, the eight-digit contents of Ad+1 and Ad, and CY, and places the result in R
and R+1. CY will be set if the result is greater than FFFF FFFF.
