Finding Two's complement of a number

Statement: Find the 2's complement of the number stored at memory location 4200H and store the complemented number at memory location 4300H.

Sample problem: (4200H) = 55H Result = (4300H) = AAH + 1 = ABH Source program: LDA 4200H : Get the number CMA : Complement the number ADI, 01 H : Add one in the number STA 4300H : Store the result HLT : Terminate program execution
