Add two decimal numbers of 6 digit each

Statement: Two decimal numbers six digits each, are stored in BCD package form. Each number occupies a sequence of byte in the memory. The starting address of first number is 6000H Write an assembly language program that adds these two numbers and stores the sum in the same format starting from memory location 6200H.

Source program : LXI H, 6000H : Initialize pointer l to first number LXI D, 6l00H : Initialize pointer2 to second number LXI B, 6200H : Initialize pointer3 to result STC CMC : Carry = 0 BACK: LDAX D  : Get the digit ADD M  : Add two digits DAA : Adjust for decimal STAX.B : Store the result INX H : Increment pointer 1 INX D  : Increment pointer2 INX B : Increment result pointer MOV A, L CPI 06H : Check for last digit JNZ BACK  : If not last digit repeat HLT : Terminate program execution
