Problem: To find maximum of two 16-bit numbers using 8086 Microprocessor.

Algorithm:

1. Move the first number to register AX.
2. Move the second number to register BX.
3. Compare the content of register AX and BX if no carry goto step 5 otherwise goto step 4.
4. Move the content of register BX to the register AX.
5. Move the content of register AX to the memory location.

Program:

	MOV     AX, [0600]
	MOV     BX, [0602]
	CMP     AX, BX
	JNC **
	MOV     AX, BX
	** MOV [0604], AX
	HLT

Observation:

    INPUT:
    0600: 14
    0601: 12
    0602: 23
    0603: 11

    OUTPUT:
    0604: 23
    0605: 11

Hence, we successfully find the maximum of two 16 bit numbers using 8086 Microprocessor.
