Microprocessors likeand many other microcontrollers could be easily operated via simple instructions of assembly languages. I suppose so, but it’s not clear because there’s no a label named “next”. The MASM prpgrams file could be downloaded from any of the links given below: Keep pressing enter when program asks for object file name or run file name during compilation and linking. But we can piece it together: In the next step the values are added and and result 03 could be seen in AX register itself.

Well, even with the new code it seems that there’s no palindrome checking, at least at first glance. So all this code does is display a message to the user prompting them to enter a string, terminated by a line feed 0dh and it reads the string in to location str.

The program could be edited as per needs for displaying more terms. Since mazm comparison is made by a subtraction of AL minus 0Dh, the match would be successful when the result is zero.
