; Initialize: Set up memory pointer and counter LXI H, 2000H ; HL points to the start address of the array MOV B, M ; Load array count into B DCR B ; Decrement B for loop count INX H ; HL points to the first data element MOV A, M ; Load the first data element into A LOOP: INX H ; Next element CMP M ; Compare Accumulator (A) with M JNC NEXT ; If A >= M, skip MOV A, M ; If A < M, replace A with M NEXT: DCR B ; Decrement loop counter JNZ LOOP ; If B != 0, continue checking HLT ; Stop; the largest number is now in A It can process, read, or write 8 bits of data simultaneously

The address is stored in a register pair (e.g., MOV A, M ).

: The primary 8-bit register used for arithmetic and logic operations. General-Purpose Registers : Six 8-bit registers ( ) that can be paired ( ) to handle 16-bit data. Program Counter (PC)

Gaonkar heavily emphasizes the register organization of the 8085, categorizing them by their accessibility and function.
