between PUSH and POP instruction with example illustrating the use of these
instructions.
- What
is CALL operation? How does it differ with JUMP operation?
- Write
an assembly language program to find the greatest number in an array in using 8
bit microprocessor. (Assume appropriate array data and address where minimum
array size of 20 should be considered.)

bit microprocessor. (Assume appropriate array data and address where minimum
array size of 15 should be considered.)

program for 8085 microprocessor to find largest element of array and store in
memory location 4005h.

LXI and CMP instruction. Write an assembly language program for 8-bit
microprocessor to divide 8 bit data stored in memory location 8050 by 8 bit
data stored in 8051 and store the quotient in 8052 and remainder in 8053.
