Question

Hello! I'm working with MASM assembly language and was wondering if someone would be able to help me with this problem. The instructions are:

The first loop is going to prompt the user to enter 10 DWORD values into an array. It will use a symbol to calculate the size of the array. The array will be initialized to zero. The second loop is going to use indirect or indexed addressing to reverse the elements of an integer array in place. The third loop is going to display the contents of the reversed array. Side note, The display is suppose to show "Enter Number 1:".."Enter Number 2:"..all the way to "Enter Number 10:" I am having difficulty incrementing the number inside of the enter number prompt.

Below is what I have so far, any help is greatly appreciated!!

INCLUDE Irvine32.inc
.DATA
Message0   BYTE "Welcome to Pat Programmer's Array Reverse",0dh,0ah,0
Message1   BYTE "Enter Number ",0
Message2   BYTE "Reverse Order",0dh,0ah,0
MessageSize = ($ - Message1) - 1
NumberToGet = 10
.CODE
main PROC
   call   clrscr
   mov       edx, OFFSET Message0
   mov       ecx, NumberToGet
