Practical No. 8 (A) : Address Label Mnemonics Hexcode Comment

This document contains two assembly language programs to add the first 10 numbers stored in memory locations on an 8085 microprocessor. The first program loads address 800H to get a count, loads HL with address 8010H, clears the accumulator, adds the memory values, increments pointers, and stores the result at 9000H. The second program loads a value from 2050H, uses it to initialize registers, adds memory values from 2051H incrementing the pointers each time, and stores the final values in 3050H and 3051H.
