The program should be written in Marie simulator.

Write an assembler program that will perform the \'while loop\' logic

read in a number that will be your LCV (loop-control-variable)

each time through the loop, print out the LCV

Example: you enter a 5

print out 5

              4

              3

              2

              1

The program should be written in Marie simulator.

remember, with a while loop, it is possible for the while loop won\'t run (if the LCV is incorrectly initialized)

Solution

. MODEL SMALL

.STACK 100H

.DATA

PROMPT_1 Db \'enter the number:$\'

PROMPT_2 db,odh,oah, \'the number is :$ \'

.CODE

MAIN PROC

MOV AX,@DATA

Move DS,AX

LEA DX,PROMPT_1

MOV AH,9

INT 21H

Mov AH,1

INT 21H

MOV BL,AL

LEA DX,PROMPT_2

MOV AH,9

INT 21H

TEST BL,01H

JNE @ODD

MOV AH,2

MOV DL,\"E\"
