The program must start at address x$3000.$ Here$$s how the program must behave:

$1.$ The program sends a newline to the console and then prints $$Enter First Number $(4$ binary digits$)$: $,$ which serves as a prompt to tell the user that the program is waiting for input. The prompt string is a string, followed by a single space.

$2.$ The user types a four$-$digit binary number on the keyboard. As the numbers are typed on the keyboard they should be echoed onto the console window. Any illegal input values are ignored after they are echoed. The program must check and accept only $0$ or $1$ numerical digits. The program should recognize the entry as complete when it sees $4$ valid digits.

$3.$ The program sends a newline to the console and then prints $$Enter Second Number $(4$ binary digits$)$: $,$ which serves as a prompt to tell the user that the program is waiting for input. The prompt string is a string, followed by a single space.

$4.$ The user types a four$-$digit binary number on the keyboard. As the numbers are typed on the keyboard they should be echoed onto the console window. Any illegal input values are ignored after they are echoed. The program must check and accept only binary numerical digits. The program should recognize the entry is complete when it sees $4$ valid digits.

$5.$ If the user types the character $$q$$ at any time the program should display a newline and the string $$Thank you for playing!$$ and then Halt.

$6.$ The program will perform an OR function on the first number and second numbers, of the values that have been entered on the keyboard. These user$-$entered numbers must be converted to binary for

$1$

the function. The program then converts this largest binary number to a four$-$digit binary number and converts the digits to ASCII code.

$7.$ The program sends a newline to the console and then prints the following on the console:

The OR function of the two numbers is: zzzz

where zzzz is the four$-$digit binary number. A linefeed $($newline$)$ is printed at the end of the string. $($Your code will not print in boldface, of course; that$$s just used for emphasis here.$)$

$8.$ The program returns to step $1.$

Do not use subroutines $($the JSR instruction$)$ for this assignment. $20$ Points will be deducted if you do$.$
