Q.1 Explain the usage of registers in MUL and DIV instructions for
8-bit and 16-bit multiplication with a register (say cl/c) is
provided as the only operand?
Q.2 Write a sequence of instructions to set and clear the following
FLAGS:
Q.3 Explain the difference between LOOP and LOOPE instruction with
the help of a program.
Q.4 Will the following code jump to the label named Target (Yes /
No)? Explain reason in each.
mov ax, 8109h
camp ax, 26h
Jg Target
add ax, 8000h
Target:
Ans:
No, because the jg is used with signed value and
(8109h is negative, and 26h is positive.)
Q.5 Write a program to sequentially search the array LIST1 of 20
elements of WORD type. Return Index number (count 0 as first index)
if search is successful otherwise display a message indicating the
absence of a key.
