Question
I'm testing out pseudo-solved problems to better understand MASM based assembly, but I'm getting some errors in the following:
Write a program that clears the screen, locates the cursor near the middle of the screen, prompts the user for two integers, adds the integers, and displays their sum. Repeat the same steps three times, using a loop. Clear the screen after each loop iteration.
Based on question 4 of chapter 5 of Assembly Language for x86 Processors (7th Edition)

.model flat,stdcall
.stack 4096
ExitProcess proto,dwExitCode:dword
COUNT=3
.data
num1 SDWORD? ;variable declaration
num2 SDWORD?
string BYTE "Enter an integer:",0 ; prints on the console
string1 BYTE "The sum is:",0
sum SDWORD 0 ; initialize sum to 0
row BYTE 5 ; initialize row to 5
col BYTE 17 ;and column to 17
.code

Based on this, I assume the problem is A: How do I solve the syntax errors for num1 and num2, and B: How do I define a symbol.
Explanation / Answer
Looking at your code, i think it is trying to call the functions that are available in KIP's IRVINE32 Library.
Looking at your code, i think it is trying to call the functions that are available in KIP's IRVINE32 Library.
So just gaive a try by installing it and try including Irvine32.inc into your ASM code. INCLUDE Irvine32.inc I dont have the resources to test it. I found a perfect setup guide in kipirvine.com where it nicely explains how to setup Visual Studio for ASM. Just try to setup your environment based on that.
