Assembly Language

$(1)$ Create a masm program, LP$1$A to prompt the user to enter a number between $1$ and $9.$ Write a nested loop to print the numbers as follows:

For e$.$g$.$ if the user entered $9,$ then the output would be:

Enter a value for length: $9$

$123456789$

$12345678$

$1234567$

$123456$

$12345$

$1234$

$123$

$12$

$1$

You must create a procedure that prompts the user for input. You must create a procedure to output the numbers as required. How are any arguments passed to the procedures?

$***$This is my work so far. I$\text{'}$m having trouble figuring out how to flip the numbers. My out put looks like
