8085 Program to store 8 bit data in memory of 8085 microprocessor

Program 1:

MVI A, 52H  : Store 32H in the accumulator
STA 4000H  : Copy accumulator contents at address 4000H
HLT              : Terminate program execution

Program 2:

LXI H           : Load HL with 4000H
MVI M                   : Store 32H in memory location pointed by HL register pair (4000H)
HLT              : Terminate program execution

The result of both programs will be the same. In program 1 direct addressing instruction is used, whereas in program 2 indirect addressing instruction is used.
