Answer to Question #324201 in Computer Networks for hamudi

Question

a) Write an assembly program using MARIE's assembly Instruction set that prompts the user to enter a non-negative integer that is less than 10. The program should include a subroutine that keeps prompting until a valid value is obtained. When a valid number is entered, it will be displayed. (Hint: Use JNS & JUMPI instructions to implement the subroutine)

N.B: You should include the MARIE code in your Answer, with an explanation of each instruction in your code beside it. Example: Subt One /Subtract 1 from AC

b) Add a screenshot of the simulation, showing the result (A screenshot of the MARIE Simulator window after running the program). Instructions: - Use “ORG” instruction to start your program at address equivalent to 25610. - Use your last university ID number to input the value of X. For example, if your ID is1915161678234, then you will use the number 4 as the value of x. - Do not forget to change the representation of the Input and Output windows in the simulator to Decimal. 

Answer 1

Solution

Code:

ORG 100
JNS checkint
OUTPUT
HALT

checkint, HEX 000
INPUT
SKIPCOND 000
JUMPI checkint
JNS checkint

This only applies the condition for non-negative. Can anyone pls help me how to apply condition for less than 10 as well?
