Answer 1

Answer #1

In assembly language whenever mathematical operations or other operations the carry and overflow flags are stored in status registers..

status register generally stores the flags of sign flag(S), auxiliary flag(AC), overflow flag(O), carry flag(CY), parity flag(P) and zero flag(Z). The order depends upon what microprocessor you using.

for example in 8086 micro processor flags are assigned in this way:

d15

d14

d13

d12

d11

d10

d09

d08

d07

d06

d05

d04

d03

d02

d01

d00

O

D

I

T

S

Z

AC

P

CY
