Problem: To find minimum of two 16bit 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 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
	JC **
	MOV     AX, BX
	** MOV [0604], AX
	HLT

Observation:

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

    OUTPUT:
    0604 : 14
    0605 : 12

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