Program : Write a program to perform a one byte BCD addition.
Solution :
It is consider that the operands are in BCD form, but the CPU considers it as hexadecimal and accordingly performs addition operation. Assume the following example for addition. Carry is set to be 0.
Actual result after addition considering hex operand
In this program, the DAA instruction is used after ADD. In similar manner, DAS can be used after instruction SUB.
