This video tutorial explains ADC (addition with carry) instruction for 8086 microprocessor in assembly language. ADC instruction is used with example programs which are executed in emu8086 environment. This video tutorial explains the example along with the usage of carry flag in status register . The state of the CF flag represents a carry from a previous addition. When an immediate value is used as an operand, it is sign-extended to the length of the destination operand format. The ADC instruction does not distinguish between signed or unsigned operands

good explain sir with example and good use of emulator
Thank you for appreciation!! Subscribe and promote my channel in community of same interest!!
good explanation, thanks
Thank you so much. I am happy to know that it was useful for you.
thank you for ur help
Glad it helped
Thanks teacher
You are welcome..I am pleased to know that it was useful for you.
Pls make video on adding two no. And storing in another register
thanks sir
Why don't we just use adc all the time to prevent carry lost?
Because we do not want to include ADC every time. For example, we are adding two numbers, and previously a carry is present from the previous operation. So, we should use ADD because if we use ADC it will add the previous carry and the result would not be simply the summation of those numbers. Rather It will be one higher than the sum. So, that's why we should use ADD. I hope that I answered your question.
@@LearnOnline1 so the carry will be lost outside of operations if we dont carry it , but when do we know to use adc and when to use add to prevent these losses?
@@finneko-ai when you are adding three numbers or always clear carry first then use ADC. Otherwise you can use add
@@LearnOnline1 so i should always use add, unless its an carry that i need? and what if the overflow is bigger than 1?
@@finneko-ai overflow is something else. Thats not should be taken care in case of add and adc. However. Your rest of point is valid.
But the result is not the real result of BX+CX, when using ADC BX,CX!!???
