Problem: To find the square of an 8-bit number using 8085 Microprocessor.

Algorithm:

1. Load the register H with value 20H and the register L with value 50H and the value of accumulator with 00H.
2. Load the content of register B with the value taken from memory.
3. Add the content of M in accumulator A and decrement the value of register B by one.
4. Check if value of register B is 00 if yes then store result at memory location otherwise goto step 3.
5. Terminate the program.

Program:

	MVI     L 50
	MVI     H 20
	MVI     A 00
	MOV     B, M
	**ADD   M
	DCR     B
	JNZ **
	STA     3050
	HLT

Observation:

    INPUT:
    2050 : 03

    OUTPUT:
    3050 : 09

Hence, we successfully find the square of an 8-bit number using 8085 Microprocessor.
