microprocessor systems applications

There is a need to write a program which computes the cube of the number entered from the keyboard. The number can be any number between 0 and 9. For example, if the number entered from the keyboard is 4, the result should be computed as 43=64. If the entered character is not in between 0 and 9, the program should recheck the key press. The computation should be based on the LOOK-UP TABLE approach. The program should also store the result into the data segment area with variable named as "Output", Interrupt services 01 and 00 should be used to check key press and get the character, respectively. The ASCII codes of numbers 0. 1, ......9 are 30H, 31H, 39H, respectively. Service 01: MOV AH, 01 Service 00: MOV AH,00 INT 161 INT 16H Service 01: When a key is pressed. ZF=0. Otherwise. ZF=1. Service 00: The ASCII code of key is stored into AL. Complete the following program to achieve this task.
